U.S. Army to Deploy Over 1,000 Switchblade 600 Drones Under Replicator Program

 The U.S. Army plans to deploy more than 1,000 Switchblade 600 drones over the next year as part of the Replicator initiative. This program, spearheaded by the Pentagon, aims to field thousands of uncrewed systems. General James Mingus, the Army’s vice chief of staff, disclosed this quantity during a House Appropriations defense subcommittee hearing on June 21 at the Defense Innovation Unit’s headquarters in Mountain View, California.

Manufactured by AeroVironment, the Switchblade 600 loitering munition is among the initial systems the Defense Department will procure through the first tranche of the Replicator program. It is the only system officials have identified by name so far. Other systems include an unspecified fleet of maritime drones, uncrewed surface vehicles, and counter-drone systems.

Replicator, announced by Deputy Defense Secretary Kathleen Hicks last August, has two main objectives. In the short term, the Pentagon aims to deploy large numbers of expendable drones to counter China. The larger goal is to establish a sustainable process for acquiring technology to meet the department’s urgent operational needs.

The Pentagon plans to allocate $1 billion to the Replicator effort during fiscal years 2024 and 2025, with funds sourced from prior year appropriations, a reprogramming request, a national security supplemental approved in August, and the department’s yet-to-be-approved FY-25 budget proposal.

Switchblade drones have seen significant use on battlefields in Russia, Syria, and Iraq. The Army initially intended to procure the system through its Low Altitude Stalking and Strike Ordnance program in smaller quantities. In October, the Army announced plans to purchase 100 Switchblade drones for testing and deployment within its units.

General Mingus highlighted the collaboration behind this innovation during the hearing, noting that the Switchblade was included as part of Replicator Tranche One and will now be scaled up to over 1,000 units in the coming year.

Deputy Defense Secretary Hicks announced last month that the department began fielding Replicator systems to Indo-Pacific Command in early May. However, the Pentagon has not disclosed the specific systems or quantities fielded.

“This demonstrates that warfighter-centric innovation is not only feasible but is also yielding tangible results,” Hicks stated. “As we deploy these systems, our comprehensive capability development process continues.”

Russia Deploys S-500 Prometheus in Crimea to Safeguard Key Assets

 Russia has reportedly deployed elements of its advanced S-500 air defense system to Crimea following successful Ukrainian strikes on the S-400 missile system. This move raises questions about whether Russia is exposing its still combat-untested system to potential Ukrainian attacks.

Currently, Russia operates only one active S-500 regiment, which consists of two battalions with two air-defense batteries each. The specifics of which elements have been moved are unclear, as such systems have multiple operational components, including command posts, radars, and launchers.

The S-500 may have been deployed to protect the critical Kerch Bridge in Crimea. This bridge, vital for connecting Crimea to mainland Russia, has been a frequent target of Ukrainian attacks. The S-500 is designed to replace the S-400 and the A-235 ABM systems, providing advanced defense against modern aerial threats, including stealth jets, hypersonic missiles, and satellites.

Ukraine continues to target Crimea, complicating Russia's efforts to maintain control. Attacks have focused on air defenses, bridges, rail links, and power supplies, including significant hits on the Kerch Bridge, impacting Russia’s ability to transport heavy military equipment.

The S-500 Prometheus is a significant leap in Russian air defense technology, boasting the ability to engage targets at ranges up to 600 kilometers. Its sophisticated radar system can track and target stealth aircraft, hypersonic missiles, and low-orbit satellites, providing a robust defensive capability.

The S-500 system includes four radar vehicles per battery and uses multiple frequencies to detect stealth aircraft. It can engage 10 targets simultaneously with a response time of three to four seconds, faster than the S-400.

US to Supply Taiwan with 1000 Armed Drones Amid Rising Tensions with China

 The United States has approved a $360 million sale of over 1,000 small armed drones to Taiwan, significantly enhancing Taiwan's asymmetric defense strategy against China. The U.S. Defense Security Cooperation Agency (DSCA) announced on June 18 that Taiwan will receive 720 Switchblade drones and related fire control systems valued at $60.2 million. Additionally, Taiwan will acquire up to 291 Altius 600M loitering munitions and associated components for $300 million.

This sale comes as Taiwan awaits previously ordered military equipment, including Abrams tanks, F-16 Vipers, and advanced munitions from Washington. Despite adhering to the 'One China' principle, the U.S. is legally obligated to provide Taiwan with defensive tools against Chinese aggression. This arms sale has drawn criticism from Beijing, which accuses the U.S. of turning Taiwan into a "powder keg."

The drone sale is crucial for Taiwan's asymmetric warfare strategy, which relies on unconventional weapons to deter a Chinese invasion. Taiwan's National Defense Report emphasizes increasing resilience and self-sufficiency, prioritizing domestic defense, and enhancing its "all-out defense" capabilities.

The U.S. Indo-Pacific Command's "Hellscape" strategy aims to deploy drones to distract China during a Taiwanese invasion, allowing U.S. forces time to respond. Admiral Samuel Paparo outlined this strategy, which involves flooding the Taiwan Strait with unmanned submarines, surface ships, and aerial drones to impede a Chinese invasion fleet.

Taiwan's recent interest in drones was likely influenced by their successful use in Ukraine, where U.S.-supplied Switchblade UAVs helped repel Russian forces. Taiwan has also developed its own drones, such as the Chien Hsiang loitering munitions, capable of targeting diverse radar systems deployed by China.

The Switchblade 300, known for its low-cost, lightweight, and precision-guided capabilities, can be deployed quickly from various platforms and has a range of 30 kilometers. Its unique abort function allows it to self-destruct if necessary, minimizing casualties.

The Altius-600M loitering munition, larger than the Switchblade 300, can be launched from land, air, or sea and features multiple seekers and warhead options. It boasts twice the loitering time and range of current loitering munitions and can operate in swarms, enabling a single operator to control multiple drones simultaneously.

Taiwan thanked the U.S. for the drone sale, marking the 15th arms deal between the two since 2021. Taiwan's Presidential Office spokesperson, Karen Kuo, emphasized the importance of strengthening self-defense and asymmetric warfare capabilities to uphold democracy and international order.
