US Air Force to Arm C-17 Globemaster with Hypersonic Missiles: Boeing Unveils New 'Revolver' Launch System

 The US Air Force's second-largest airlifter, the C-17 Globemaster III, is set to gain significant offensive capabilities. Boeing has introduced the "Revolver" launch system, which will enable the aircraft to launch multiple hypersonic missiles from its cargo bay. This adaptation aligns with the USAF's strategy to enhance the offensive capabilities of airlifters like the C-17 and C-130J, particularly in the Indo-Pacific region where conflicts with China may arise.

The USAF's plan anticipates that cargo and tanker planes will need to provide more than logistical support in potential confrontations with powerful adversaries like Russia or China. The Revolver system is designed to integrate X-51A Waverider hypersonic cruise missiles, allowing the launch of 12 missiles using an advanced drum and electromagnetic catapult mechanism. These missiles, known for their scramjet engines, can exceed Mach 5, offering long-range precision strikes.

Originally intended for the B-52 Stratofortress, the X-51 program involved collaboration among the Air Force, DARPA, NASA, Boeing, and Pratt & Whitney Rocketdyne. Although the X-51 was scheduled for mid-2020s service, delays have pushed back its deployment.

In 2013, the X-51A achieved a historic hypersonic flight, maintaining scramjet power for three and a half minutes at Mach 5.1. Boeing showcased the Revolver concept in a video, emphasizing its versatility and enhanced capabilities for the C-17.

The C-17, capable of transporting 102 paratroopers, 54 patients, or 85 tons of cargo, is a critical asset for global operations. With the Revolver launcher, it will also serve in missile deployment, enhancing its role in modern military logistics.

Boeing's efforts in hypersonic technology also include the DARPA Glide Breaker program, aiming to develop a hypersonic interceptor prototype. Meanwhile, China's advancements in hypersonic weaponry pose a significant challenge, with the US making substantial investments to close the gap, including a $756 million contract with Lockheed Martin for ground-based hypersonic systems.

The USAF tested a hypersonic cruise missile in the Pacific in March, demonstrating its commitment to remaining competitive. Recent exercises with the C-17 have involved loading and unloading missile cradles, illustrating its flexibility to operate from various airfields.

The Rapid Dragon project explores deploying cruise missiles from cargo planes, allowing C-17s to carry out offensive missions with minimal modifications. This approach is seen as cost-effective, providing strategic advantages by leveraging existing transport fleets.

China is wary of this capability, recognizing the difficulty in tracking cargo planes capable of launching missiles from unexpected locations. Overall, the C-17's transformation into a missile-carrying aircraft exemplifies the evolving strategies in modern warfare, with significant implications for global military dynamics.

Northrop Grumman’s Manta Ray: Revolutionary Underwater Drone with Extended Capabilities

 

Northrop Grumman’s Manta Ray submersible underwater drone has been the subject of considerable interest for some time.

Aurora Advances to Next Design Phase for DARPA's High-Speed Vertical Takeoff X-Plane

 

Aurora Flight Sciences has completed the conceptual design phase of an innovative vertical-takeoff-and-landing aircraft for the Pentagon's SPRINT program and is now entering the preliminary design stage.

The SPRINT (Speed and Runway Independent Technologies) program aims to develop a vertical takeoff aircraft, also referred to as the X-plane, capable of achieving speeds between 400 and 450 knots. This is significantly faster than the V-22 Osprey, which has a maximum speed of 270 knots. The aircraft must be able to hover stably, transition seamlessly from hovering to forward flight, and feature a distributed energy system that powers all propulsion technology during these transitions.

DARPA has given companies the flexibility to design the aircraft as crewed, uncrewed, or autonomous. In November 2023, DARPA awarded six-month contracts to four companies—Aurora (a Boeing subsidiary), Bell Textron, Northrop Grumman, and Piasecki Aircraft Corp.—to begin their conceptual designs.

On April 30, Aurora received a $25 million contract modification to continue developing its version of the SPRINT aircraft. This significant funding boost follows an initial $4.2 million allocation. Currently, Aurora is the only company to receive further funding to advance in the SPRINT program, but more awards may follow. DARPA plans to eliminate at least one company from the competition after the conceptual design phase.

Aurora’s blended-wing design incorporates three embedded lift fans for vertical flight, transitioning to embedded engines for forward flight. This design reduces drag and allows high-speed travel, making it ideal for air mobility and special operations missions. New concept art from Aurora shows an uncrewed aircraft with a composite exterior capable of cruising at 450 knots. The design is adaptable, with the potential to add more lift fans or create a crewed version if military requirements change.

Aurora aims to complete the preliminary design review within a year and conduct the first flight in three years. Bell Textron, another competitor, is pursuing a tiltrotor design similar to the Osprey.

In addition to the SPRINT project, DARPA awarded Aurora an $8.3 million contract modification to continue developing an experimental heavy cargo seaplane, the Liberty Lifter.
