Pentagon Recommits to Sentinel Nuclear Missile Amid Rising Costs and Program Overhaul

 

The Pentagon remains dedicated to developing the LGM-35A Sentinel intercontinental ballistic missile despite escalating costs, instructing the U.S. Air Force to restructure the program to manage expenses. The Sentinel, made by Northrop Grumman, is now projected to cost $140.9 billion, an 81% increase from the initial $77.7 billion estimate. Without modifications, costs could reach $160 billion. This restructuring will delay the program by several years. 

William LaPlante, undersecretary of defense for acquisition and sustainment, emphasized the necessity of modernizing nuclear forces despite the costs. The Sentinel is set to replace the aging Minuteman III missile. In January, the Air Force reported severe cost overruns, prompting a critical Nunn-McCurdy breach review. LaPlante decided to continue with the Sentinel, citing its essential role in national security and the lack of cheaper alternatives.

Significant changes are expected, including rescinding the program's Milestone B approval and ordering a complete restructure to address cost overruns and management issues. The per-unit cost, initially $118 million in 2020, has risen to about $214 million, including additional components.

 Andrew Hunter, the Air Force’s assistant secretary for acquisition, technology, and logistics, supported LaPlante's decision and pledged to devise a restructuring plan over the next few months. This plan will likely take 18 to 24 months for the Pentagon's approval.

Most cost overruns are linked to Sentinel’s command and launch segment, including missile silos and launch control centers. The Air Force aims to scale back these facilities to reduce costs and transition timelines from the Minuteman III system to the new Sentinel facilities. Northrop Grumman continues to make progress on the Sentinel, achieving key milestones in design, development, and testing.

 The Pentagon now has better information on Sentinel's complexities, leading to more accurate cost estimates. The Air Force has established oversight committees and executive officers to manage its nuclear enterprise, ensuring the Minuteman III’s sustainability during the interim period.

Gen. Jim Slife, the Air Force’s vice chief of staff, noted that the most challenging decisions regarding program cuts would be made after establishing the new baseline costs, which are expected to emerge in the next few years.

North Korea Tests Multi-Warhead Missile, Escalating Regional Tensions

 On June 27, North Korea announced that it successfully tested a multi-warhead missile, a development that could pose significant threats to South Korea, Japan, and the United States if confirmed. This test is seen as an attempt by North Korea’s leader, Kim Jong Un, to evade missile defenses in South Korea and the US, fulfilling his long-standing ambition for a multi-warhead missile.

The announcement from North Korean state media, KCNA, contradicted South Korea’s assessment of a failed weapon test from the previous day. KCNA reported that the test on June 26 involved the separation and guidance control of individual mobile warheads, marking a significant step in advancing missile technologies.

The test aimed to secure Multiple Independently Targeted Re-entry Vehicle (MIRV) capability, enabling the delivery of multiple warheads to different targets. The missile’s decoy was detected by radar, and the mobile warheads were successfully guided to three target coordinates.

Reports indicate that North Korea used a modified Hwasong-16 booster for a shortened-range test to validate the release of independent warheads. This test, the first of its kind for North Korea, is considered a preliminary step by international observers.

KCNA quoted the North Korean Missile Administration, highlighting the test as part of a full-scale effort to enhance missile capabilities and technologies. Kim Jong Un has listed a multi-warhead missile among his priorities, alongside hypersonic weapons, spy satellites, solid-fuel ICBMs, and submarine-launched nuclear missiles, all of which are in various development stages.

This development is particularly significant amid rising tensions between North Korea and NATO, especially after North Korea’s provocative actions, such as sending waste-filled balloons across the 39th parallel and issuing multiple warnings against US-South Korea cooperation.

Recently, North Korea revived defense cooperation with Russia, hosting Russian President Vladimir Putin and signaling readiness to send troops to fight in Ukraine. Amid this backdrop, the MIRV test gains critical importance, potentially elevating North Korea’s threat level, especially if the warheads are nuclear.

Despite international sanctions, North Korea is believed to have assembled 40-50 nuclear warheads. In November, Kim Jong Un urged exponential nuclear weapon production and aligning with nations opposing the US in a “New Cold War.”

North Korea’s test follows India’s recent MIRV test, which unsettled its nuclear-armed neighbors, Pakistan and China. Unlike South Korea, which lacks nuclear weapons, this development significantly heightens the threat.

MIRVs can overwhelm missile defenses by deploying multiple warheads simultaneously, making interception more difficult. This sophisticated technology requires advanced capabilities, which some US critics believe North Korea might be receiving from Russia, given their military exchanges.

While the world advocates for nuclear non-proliferation, the development of MIRV technology has faced criticism. Hans Kristensen of the Federation of American Scientists expressed concerns about the increasing number of countries acquiring MIRV capabilities, warning that it could escalate nuclear tensions.

Similar concerns apply to North Korea, which has issued several nuclear threats. The Washington-based Wilson Center noted that MIRVs would significantly undermine US defense capabilities against a North Korean nuclear strike.

China to Expand Nuclear Arsenal by 90 Warheads by End of 2024

 China is set to significantly increase its nuclear warhead count by at least 90 by the end of 2024, according to the Stockholm International Peace Research Institute (SIPRI). SIPRI, which has been tracking global armaments for many years, reports that China's nuclear arsenal has grown from 410 warheads in 2022 to approximately 500 currently. This expansion highlights China’s rapid efforts to enhance its military power, although it still lags behind the US and Russia.

Globally, there are 3,904 nuclear warheads ready for launch, with an additional 5,681 in storage, totaling an alarming 9,585 warheads. Among smaller nuclear powers, India holds 172 warheads, Pakistan has 170, North Korea has about 50, and Israel maintains around 90. North Korea, with sufficient nuclear material, could potentially increase its arsenal to 90 warheads.

The transparency of nuclear arsenals has decreased since the US and Russia paused the New START Treaty in 2023, which previously aimed to limit these arsenals. This has contributed to an arms race, with nations enhancing their nuclear capabilities and developing new launchers and ballistic missile submarines. The ongoing investigations into Iran’s nuclear development and escalating international tensions further exacerbate the situation.

Russia and the United States currently possess the largest number of nuclear warheads, with 5,580 and 5,244 respectively. They account for nearly 90% of the world's total nuclear arsenal. Of these, 3,904 warheads are deployed on missiles and aircraft, marking an increase of 60 from the previous year. This includes 1,710 from Russia and 1,770 from the United States. China is estimated to have 24 warheads deployed on missiles.

SIPRI Director Dan Smith highlights that while the total number of nuclear warheads globally continues to decline as Cold War-era weapons are dismantled, there is an annual increase in the number of operational warheads. This trend is expected to accelerate in the coming years, raising significant concerns.

NATO Secretary General Jens Stoltenberg has emphasized ongoing discussions about possibly deploying additional nuclear weapons within the alliance. He underscores the need to demonstrate NATO’s nuclear capabilities to potential adversaries. Stoltenberg notes that China, Russia, and North Korea are the main challenges for NATO and points out China’s significant nuclear arsenal expansion. He forecasts that by 2030, China's nuclear stockpile could reach about 80% of the size of the US and Russian arsenals.

The production of nuclear warheads involves the extraction and refinement of fissile material, primarily uranium-235 and plutonium-239. Uranium-235 is enriched from natural uranium, while plutonium-239 is produced in nuclear reactors. The fissile material is then fashioned into a core or 'pit' surrounded by a tamper and encased in a high-explosive shell designed to compress the core to a supercritical state when detonated.

The warhead’s triggering mechanism involves conventional explosives arranged to ensure symmetrical compression of the fissile core. Advanced designs may also include a neutron initiator to ensure a rapid and sustained chain reaction. The warhead is then integrated into a delivery system, such as a missile or bomb, with rigorous testing and quality control to ensure reliability and safety. Modern warheads include sophisticated electronics for arming, fuzing, and firing, as well as safety mechanisms to prevent accidental detonation.

Throughout the production process, strict security and non-proliferation measures are enforced to prevent unauthorized use or dissemination of nuclear technology, with oversight by organizations such as the International Atomic Energy Agency (IAEA).

F-35 Jets Stationed in Norway's Mountain Hangars for Defense Against UAV Attacks Post Su-57 Incident

 Recently, photos emerged online showing underground shelters at Norway’s Bardufoss Air Force Base, captured during a Norwegian Air Force exercise. These images featured fifth-generation F-35A Lightning II fighter jets practicing in mountain-based shelters. Norway, a NATO member, has F-35 aircraft certified to carry tactical nuclear weapons, making these underground facilities highly secure against missile and drone attacks.

Since joining NATO, Norway and the Nordic region have experienced almost continuous military exercises, underscoring the ongoing militarization of Scandinavia amid escalating threats of potential Arctic conflicts.

Bardufoss, Norway’s oldest airbase, has a rich history dating back to World War II. Initially used by the Allies, it was later taken over by German forces who launched fighter, bomber, and reconnaissance missions from the base. Today, Bardufoss, located in Målselv Municipality, Troms og Finnmark county, is a strategic military airbase operated by the Royal Norwegian Air Force, critical due to its proximity to the Arctic.

The airbase features a single runway, 10/28, stretching 2,443 meters (8,015 feet), accommodating various military aircraft, including fighter jets, transport planes, and helicopters. Bardufoss supports a wide array of offensive and defensive operations.

The 139th Air Wing, stationed at Bardufoss, includes the 337 Squadron with NH90 helicopters and the 339 Squadron operating Bell 412 helicopters. These units are vital for search and rescue missions, anti-submarine warfare, and troop transport. Additionally, the base hosts a detachment from the Norwegian Army’s Aviation Battalion, using Bell 412 helicopters for reconnaissance and medical evacuation, enhancing the base's operational capabilities.

Equipped with advanced radar and communication systems, Bardufoss ensures robust surveillance and coordination, essential for monitoring airspace and supporting NATO operations. Norway is a key NATO member, and these capabilities reinforce the alliance's northern defense posture.

The rising tensions near Russia’s northern borders have prompted NATO to conduct exercises in the region, reflecting concerns over the perceived threat from Russia. Norway has ordered 52 F-35A Lightning II aircraft from Lockheed Martin to modernize its air force, replacing its aging F-16 fleet. The F-35A, a fifth-generation multirole fighter, features advanced avionics, including the AN/APG-81 AESA radar, Distributed Aperture System (DAS), and Electro-Optical Targeting System (EOTS), providing superior situational awareness and targeting capabilities.

The F-35A is powered by a single Pratt & Whitney F135-PW-100 turbofan engine, delivering maximum thrust of approximately 43,000 pounds with an afterburner, enabling speeds up to Mach 1.6. The aircraft's internal weapons bay can house up to four air-to-air missiles or two air-to-ground munitions and two air-to-air missiles, with external hardpoints for additional ordnance. Typical armaments include AIM-120 AMRAAM, AIM-9X Sidewinder missiles, and precision-guided bombs like the GBU-31 JDAM.

In the context of recent tensions, the deployment of F-35A fighters in Norway's underground shelters at Bardufoss Air Force Base demonstrates NATO's strategic defensive measures. The increased militarization of Scandinavia and the Arctic region highlights the ongoing preparation against potential UAV and missile threats, reinforcing the region's defense infrastructure.

Russian Kazan Submarine Conducts Military Drills Near US Waters Amid Rising Tensions

The Russian missile frigate Admiral Gorshkov and the nuclear-powered Yasen-class cruise missile submarine Kazan recently conducted military exercises near Cuba, signaling to the West amid escalating tensions. The Russian Ministry of Defense announced on June 11 that these vessels were practicing the use of high-precision missile weapons in the Atlantic Ocean.

According to the Ministry, the tactical strike group, comprising the Kazan submarine and the Admiral Gorshkov frigate from the Northern Fleet, performed exercises targeting marine enemies over 600 kilometers away using computer simulations.

These drills coincided with Russia starting the second phase of tactical nuclear exercises with Belarus. Russian state media emphasized these maneuvers as a demonstration of Russia's global influence, countering Western views of its waning power. Reports indicate that the Russian flotilla was monitored by US and allied forces as it moved towards the Caribbean, at times nearing 30-90 miles from Florida.

The Russian vessels were welcomed in Cuba on June 12 for naval exercises set to last until June 17, emphasizing the historical friendship between the two nations. Despite the nuclear capabilities of these ships, Cuba clarified that they would not be armed with nuclear weapons during their stay. The US has stated that these exercises pose no direct threat.

This is not the first instance of Russian-Cuban military collaboration, with annual drills occurring from 2013 to 2020. Analysts note that the presence of the Kazan submarine, known for its stealth, could increase tensions despite US assurances. The Yasen-class submarines, including Kazan, are among the quietest and most sophisticated in the world, enhancing Russia’s defensive and deterrence capabilities.

Kazan, a Yasen-class submarine, is praised for its advanced technology and quiet operation, rivaling the US's modern submarine fleet. Designed by the Malakhit Marine Engineering Bureau and built by Sevmash Shipyard, the 13,800-ton vessel features a quieter nuclear reactor, additional sensors, and new quieting technologies. It is capable of carrying a range of missiles, including hypersonic ones, and can target enemy submarines, ships, ports, and naval bases.

US officials have acknowledged the increasing deployment of these submarines near US waters. Gen. Glen VanHerc of USNORTHCOM noted that Russia's Yasen-class submarines have been operating more frequently in both the Atlantic and the Pacific, posing a growing threat.

While the current exercises with Cuba are downplayed by US officials, military analysts express concerns about potential electronic warfare and intelligence gathering by hostile submarines. The deployment of Yasen-class submarines like Kazan in strategic locations could pose significant risks to the security of the US and its allies in Europe. 

Pakistan's Potential Nuclear Submarine Program Challenges Indian Naval Strategy

 Pakistan is considering enhancing its naval capabilities by equipping its under-construction Chinese submarines with nuclear-tipped missiles, potentially altering the strategic balance for the Indian Navy.

Delays due to fiscal constraints had postponed the acquisition of S-26 Hangor class submarines from China. Initially expected by the end of 2023, the first of these Yuan-class submarines was launched in May 2024.

Once eight of these submarines, equipped with Air-Independent Propulsion (AIP), join the Pakistan Navy, they will significantly boost the country’s offensive sea denial strategy, which emphasizes the use of submarines and missile-carrying maritime patrol aircraft. Expected to be operational by the late 2020s and early 2030s, the addition will increase the number of AIP-equipped submarines in the Pakistan Navy to 11.

Recent reports suggest that the Hangor class may not be a purely conventional attack submarine. Retired Pakistani naval officers have discussed on state television that Islamabad is aiming for an “assured” second-strike capability.

According to a Quwa report, Vice Admiral Ahmed Saeed and Rear Admiral Saleem Akhtar, both retired officials, talked about acquiring Hangor-class submarines from China. Saeed suggested these submarines would be a "hybrid," balancing conventional attack capabilities with nuclear potential.

While retrofitting the Hangor class with nuclear reactors is unlikely, Pakistan could deploy Tactical Nuclear Warheads (TNWs) on these submarines. Building nuclear-powered submarines is costly and complex, as noted by retired Commodore Anil Jai Singh, making it improbable even with Chinese assistance.

Pakistan has been developing TNWs since its first nuclear test in 1998. These smaller, portable weapons are designed for battlefield use rather than as strategic deterrents. The Hangor-class submarines will likely use a variant of the Babur-3 Sea-Launched Cruise Missile (SLCM), first tested in 2018 with a range of 450 km. The Babur-3 is a critical component of Pakistan’s “credible second-strike capability,” according to the Inter-Services Public Relations (ISPR).

Vice Admiral Saeed emphasized that while the Hangor class is not a dedicated nuclear platform, the Pakistan Navy seeks to fire nuclear weapons from the sea, potentially requiring just one or two dedicated submarines. However, the Hangor class would primarily manage conventional roles and only strategic duties part-time.

Commodore Singh expressed doubts about the effectiveness of a single nuclear-armed submarine in the Pakistan Navy. He suggested that China might lease one to Pakistan in the future, but this remains uncertain.

Indian Navy's Concerns

While Pakistan cannot independently design and develop a nuclear-powered submarine, it may be exploring the possibility as part of a long-term strategy. China's support in arming Pakistan with such a submarine would challenge the Indian Navy’s dominance in the Indian Ocean Region (IOR). China has already been supplying submarines to Bangladesh, Pakistan, and Myanmar, creating a competitive underwater environment in the IOR.

Retired Captain Anurag Bisen highlighted that a Pakistani submarine armed with TNWs would constrain the Indian Navy's deployment of its aircraft carriers until the submarine is accounted for.

India has been adopting a flexible deterrence approach against China and Pakistan. In March, New Delhi successfully tested the long-range ballistic missile Agni-V, featuring Multiple Independently Targetable Re-entry Vehicle (MIRV) technology, enhancing the survivability of its nuclear missiles.

Despite the potential threat from TNWs, Commodore Singh remains optimistic, questioning whether Pakistan has considered India's likely retaliation, as stated in its nuclear doctrine. Using TNWs is complicated and risky, making their actual deployment a significant gamble for Pakistan.

US Test-Fires Minuteman III Missiles Amid Call for Modernization of Nuclear Arsena

The U.S. military conducted test launches of two unarmed Minuteman III intercontinental ballistic missiles this week, emphasizing that these tests were not influenced by current global events. The Air Force Global Strike Command, which oversees part of the United States' nuclear triad, carried out the tests on June 4 and June 6 from Vandenberg Space Force Base in California.

Defense News has reached out to confirm the success of these tests. In the June 4 announcement, Col. Chris Cruise, head of the 377th Test and Evaluation Group, highlighted the importance of the U.S. nuclear program for global security, stating that the test demonstrated the readiness and reliability of the ICBM system and underscored the continuous alert status maintained by U.S. forces.

The missiles' reentry vehicles traveled approximately 4,200 miles to the Ronald Reagan Ballistic Missile Defense Test Site on the Kwajalein Atoll in the Republic of the Marshall Islands. These reentry vehicles, which carry nuclear warheads, are designed to separate from the missile, travel through space, and reenter the Earth’s atmosphere to reach their targets.

Initially operational in the 1970s and intended for a decade of use, the Minuteman III ICBM system remains in service nearly 50 years later and will continue until the 2030s, according to Rep. Mike Rogers, R-Ala., chair of the House Armed Services Committee. Earlier in the month, the Air Force had to intentionally destroy an unarmed ICBM during a test due to an anomaly.

Rep. Rogers emphasized the need to modernize the aging nuclear deterrent, advocating for the replacement of the Minuteman III and other nuclear systems with modern technology. The Air Force is developing a new ICBM, named Sentinel, though the program faces delays and cost overruns, with the first test flight now scheduled for February 2026.

Sen. Elizabeth Warren of Massachusetts and Rep. John Garamendi of California have expressed concerns over the Air Force’s inconsistent timeline for the Sentinel program, noting that while the Minuteman III is expected to remain viable until the mid-2030s, the Air Force plans to maintain it for 15 to 20 more years as the Sentinel is phased in. The Minuteman III will thus be relied upon until at least 2036.

Russia Issues Nuclear Threats if NATO-Backed F-16s Strike Within Its Borders

 

As NATO's support for Ukraine grows, Russia has issued a stark warning to "small countries with dense populations" about the potential for nuclear retaliation if F-16 jets hit targets inside Russia. This follows comments from the Dutch Foreign Minister suggesting that F-16 fighters from the Netherlands could be used for such strikes.

On May 31, Dutch Foreign Minister Hanke Bruins Slot stated that the Netherlands would not object if Ukraine used the supplied F-16 fighter jets to strike Russian targets in self-defense. "If you have the right to self-defense, there are no borders for the use of weapons. This is a general principle," Bruins Slot said during an informal NATO foreign ministers' meeting in Prague.

Denmark has taken a similar stance, with Foreign Minister Lars Lokke Rasmussen noting that it is fair for Ukraine to use Danish-supplied F-16s to target military objectives within Russia. Rasmussen emphasized that Ukraine was not given carte blanche to invade Russia but to target military installations strategically.

Ukraine is set to receive F-16s from Denmark, the Netherlands, Norway, and Belgium, with the United States approving the transfer. However, Washington's approval may be needed for combat operations targeting Russian territory, as these fighters were originally sold by the US.

Social media is abuzz with speculation that F-16s will soon strike Russia, despite no official acknowledgment from the Pentagon. Pro-Ukraine bloggers and analysts express widespread jubilation over this possibility. The statements from Dutch and Danish officials reflect a growing consensus within NATO to allow Ukraine to target Russian territory with Western-supplied weapons.

Recent indications suggest that the US may have permitted Ukraine to use American munitions to strike Russia, with President Joe Biden authorizing such strikes near Kharkiv. Secretary of State Antony Blinken confirmed this on May 31, noting that the US would "adapt and adjust" to future Ukrainian requests for strikes within Russia.

Blinken did not specify if F-16s could be used for these strikes. The Biden Administration has so far refrained from allowing Ukraine to use long-range Army Tactical Missile System (ATACMS) to hit Russian targets. Other NATO allies, including France and Germany, have also authorized strikes within Russian territory, led by French President Emmanuel Macron's support for Kyiv's right to neutralize Russian military bases launching attacks into Ukraine.

These decisions come amid Ukrainian leaders' claims that restrictions on their use of weapons have allowed Russia to attack with impunity. Russia has responded with strong warnings, emphasizing its nuclear capabilities.

Russian President Vladimir Putin warned of "serious consequences" due to the escalating situation, particularly for European countries with small territories and dense populations. During a visit to Uzbekistan, Putin highlighted the risks of such nations considering strikes deep into Russian territory.

On May 31, Andrei Kartapolov, Head of the Defense Committee in the Russian lower house, stated that Moscow would respond asymmetrically to any attacks using US-supplied weaponry. Senior Russian security official Dmitry Medvedev also reiterated that Russia's threats of using tactical nuclear weapons against Ukraine are serious, cautioning that the conflict with the West could escalate into a full-scale war.

Western leaders have hesitated to supply certain weapon systems and authorize their use against Russia to avoid triggering a broader conflict between NATO and Russia. However, with Russia's ongoing aggressive actions and advances into Kharkiv, NATO states are increasingly supporting the use of long-range Western weapons to counter the Russian threat.

Dutch F-35s Assume NATO Nuclear Role; Russian Expert Calls for Nuclear Test

 

Starting June 1, 2024, the Royal Netherlands Air Force (RNLAF) will transition from F-16 Fighting Falcons to advanced F-35 aircraft for NATO’s nuclear deterrence mission, as announced by the Dutch government. This move positions the Netherlands as the first European nation to use the F-35 for this role, marking a significant upgrade in NATO’s nuclear deterrence capabilities.

On May 30, Dutch Defense Minister Kajsa Ollongren informed the House of Representatives about the transition, which underscores the Netherlands' commitment to NATO's security framework. The F-35 has undergone rigorous testing and certification, achieving initial certification for the deterrence mission in November 2023 and full certification to carry the B61-12 thermonuclear bomb in March 2024.

The transition has already seen Dutch F-35s replace F-16s in the NATO Quick Reaction Alert (QRA) detachment as of March 29, 2024. Volkel Air Base will host the new Dual-Capable Aircraft F-35 squadron, which will eventually deploy the new B61-12 bombs, reaffirming the Netherlands' dedication to NATO’s nuclear deterrence strategy.

In light of this development, Russian expert Dmitry Suslov has called for a "demonstrative" nuclear explosion to deter Western support for Ukraine. Suslov, part of the Moscow-based Council for Foreign and Defense Policy, suggests that a non-combat nuclear test could serve as a stark reminder of Russia’s nuclear capabilities and deter further Western intervention.

Suslov’s proposal, published in Profil magazine, argues that such a test would have a profound psychological impact on Western leaders, reinforcing the deterrent power of nuclear weapons. He also recommended strategic nuclear exercises and warnings to countries supplying Ukraine, suggesting potential global targeting of their assets if they retaliate.

This suggestion follows President Vladimir Putin's warning to the West against allowing Ukraine to strike deep inside Russia, which he claimed could lead to global conflict. While Suslov does not hold an official government position, his think tank’s influence on Russian policy lends weight to his proposal. The Kremlin has reiterated that Russia’s nuclear policy remains unchanged but has recently conducted tactical nuclear weapons drills in response to what it views as escalating Western rhetoric.

This development underscores the ongoing tension and strategic maneuvering between NATO and Russia amidst the broader context of the Ukraine conflict.

US Navy Enhances Sea-Based Nuclear Deterrence Amid China Tensions

 

The United States is boosting its nuclear deterrence by developing sea-based nuclear cruise missiles to counter threats from China and Russia. This initiative comes as tensions with these adversaries escalate.

Currently, the U.S. nuclear triad includes land-based intercontinental ballistic missiles (ICBMs), air-launched cruise missiles, and sea-based weapons. However, the Pentagon is now focusing on enhancing its sea-based nuclear capabilities to ensure a reliable second-strike option, crucial if land-based and air-launched systems are compromised in a first strike.

Navy Vice Adm. Johnny R. Wolfe Jr., Director for Strategic Systems, testified before the Senate Armed Services strategic forces subcommittee, emphasizing the deterrent role of ballistic missile submarines, which remain on alert and undetectable. This capability ensures the U.S. can retaliate effectively if attacked.

Alongside Air Force Gen. Thomas A. Bussiere, Commander of Air Force Global Strike Command, Vice Adm. Wolfe detailed the modernization efforts of the Navy's nuclear triad, highlighting the new sea-launched cruise missile (SLCM-N). This missile is designed to be launched from attack submarines and surface vessels, rather than just ballistic missile submarines.

Wolfe pointed out the challenges of reviving the industrial base needed for SLCM-N production and the significant investments required for concurrent nuclear modernization programs. The SLCM-N aims to counter the expanding nuclear arsenals of Russia and China, with Russia possessing nearly a thousand tactical nuclear weapons and China having around 500 nuclear warheads.

A previous Pentagon report noted that China's Jin-class ballistic missile submarines, equipped with JL-3 missiles capable of carrying nuclear warheads, are conducting near-continuous patrols in the South China Sea, posing a significant threat to U.S. security.

The introduction of the SLCM-N marks the first new U.S. nuclear weapon since the end of the Cold War, signaling to adversaries that the U.S. remains capable of responding to any nuclear threat. This development is essential for maintaining strategic stability and deterring potential nuclear attacks.

Vice Adm. Wolfe stressed the need for investments in infrastructure, human capital, and the industrial base to achieve nuclear modernization. He highlighted the necessity of balancing the SLCM-N program with ongoing Navy initiatives and the importance of continued support from Congress to deliver a reliable sea-based strategic deterrent capability.

As the U.S. transitions from Ohio-class to Columbia-class submarines, maintaining the current missile inventory and ensuring a seamless transition between the classes are critical priorities.

Sen. Deb Fischer emphasized the need for diverse deterrence options, and Wolfe concurred, noting that nuclear modernization requires careful planning and time to balance various operational needs and strategic goals.

Dutch F-35s Replace F-16s in NATO’s Quick Reaction Alert: Nuclear-Capable Interceptors on Standby

 On March 29, Dutch F-35s assumed the Quick Reaction Alert (QRA) duties previously held by F-16s, signaling a shift towards retiring the latter. Tasked with guarding the airspace over Belgium, the Netherlands, and Luxembourg, these F-35s from the Royal Netherlands Air Force (RNLAF) will rotate until May 9, with Belgian Air Force taking over thereafter.

NATO's QRA involves fighter aircraft scrambling to investigate potential airspace violations, requiring coordinated responses between reporting centers and pilots. The F-35's advanced capabilities, including powerful radar, stealth, and sensor fusion, make it a formidable interceptor, capable of identifying and engaging enemy aircraft before detection.

Operating from Leeuwarden and Volkel Air Base, the RNLAF's F-35As replace the aging F-16s, part of the phased transition towards a fleet of 52 F-35As. These aircraft, equipped with modern technology, ensure continuous readiness for rapid interception, particularly crucial amidst heightened tensions with Russia.

Despite past issues, including crashes and cost overruns, the F-35's cutting-edge features are acknowledged even by Russia-leaning experts. Furthermore, recent certification allows the F-35A to carry the B61-12 nuclear bomb, making it a dual-capable aircraft. However, this capability is currently limited to a new variant of the bomb, gradually replacing older versions.

Notably, the Dutch and Belgian air bases hosting these aircraft are also among the six NATO bases storing US-owned nuclear weapons, highlighting the strategic significance of these deployments. While details remain undisclosed, it's expected that all F-35As in the Dutch inventory will eventually be nuclear-capable, reflecting the need for operational redundancy.

Rethinking India's Nuclear Strategy: Challenges and Responses Amidst Pakistan's Growing Nuclear Assertiveness

In the wake of Pakistan's increasingly India-centric nuclear weapons policy, India faces pressing questions regarding its own nuclear stance. Former Pakistani General, often referred to as the 'Father of the Pak Atomic Bomb', recently warned of potential mayhem, urging India to reconsider its long-held No First Use (NFU) policy. As tensions escalate, how can Delhi effectively respond to these strategic shifts?

The article delves into the historical context of nuclear weaponry, highlighting the evolution from the 'Little Boy' dropped on Hiroshima to contemporary MIRV-ed ballistic missiles like India's Agni-5. With Pakistan boasting a growing arsenal, including advancements in surface-to-surface missiles (SSMs), India is urged to adapt its nuclear doctrine accordingly.

Critics argue that India's adherence to Cold War-era policies is outdated, especially in light of Pakistan's aggressive stance and China's nuanced nuclear strategies. While India has hinted at flexibility regarding NFU, concrete actions are needed to match evolving threats.

Recent developments, such as the activation of the Prototype Fast Breeder Reactor (PFBR) and successful MIRV-capable missile tests, underscore India's commitment to enhancing its nuclear capabilities. However, challenges persist, including geopolitical tensions and technological advancements.

In response to Pakistan's assertive rhetoric, India must reassess its deterrence strategy, potentially moving from NFU to a Need-Based First Use (NBFU) policy. As the region navigates uncertain waters, the article calls for a pragmatic approach to nuclear deterrence, emphasizing the imperative of aligning policy with evolving threats.

Amidst growing nuclear posturing, India's upcoming Independence Day celebrations present an opportune moment for reevaluation and recalibration of its nuclear doctrine. The article concludes with a stark reminder: in an increasingly volatile landscape, a deterrent without intent is rendered impotent. 

Northrop Grumman: Air Force Design Changes Drive Up Sentinel ICBM Costs

 A Northrop Grumman representative has attributed the significant cost increase of the U.S. Air Force's upcoming intercontinental ballistic missile (ICBM), the LGM-35A Sentinel, to design alterations by the service, particularly concerning the missile silos and connecting cables.

Originally, the Air Force planned to retain nearly all existing copper cabling, spanning approximately 7,500 miles, to support the Sentinel. However, the service later determined the necessity of upgrading to a higher-performing fiber-optic network, leading to additional costs.

Moreover, design adjustments to the launch facilities, initially conceived during the early phases of engineering and manufacturing development, also contributed to the cost escalation. The sheer scale of these changes, encompassing hundreds of launch facilities and thousands of miles of cable, resulted in substantial budgetary impacts.

The Sentinel program, aimed at replacing the aging Minuteman III ICBMs, has faced significant challenges and cost overruns. Originally projected at $96 billion with a per-unit cost of $118 million, the program's expenses have surged by at least 37%, with a current per-unit cost of around $162 million.

As a result of the cost increases triggering a Nunn-McCurdy breach, the Pentagon is conducting a review to identify the factors responsible. Despite setbacks, the Air Force remains committed to the Sentinel program, emphasizing the necessity of replacing the Minuteman III to maintain a credible nuclear deterrent.

Northrop Grumman continues its engineering and manufacturing development work on Sentinel, albeit amidst ongoing cost discussions with the Air Force. Despite the challenges, the program aims to deliver a next-generation ICBM with enhanced capabilities and reliability, ensuring the nation's strategic nuclear deterrent for decades to come.
