U.S Navy To Develop Mach 4 Hypersonic ALRRM Missile That Can Carry 150-LB Warhead

The U.S Navy is developing a new missile which will be cost-effective and travel at four times the speed of sound in a move towards procurement of advanced, but affordable, weapon systems.

The new missile, called the Air-Launched Rapid Response Missile, is being developed by Guide Tech, a subsidiary of Palladyne AI, which was awarded the contract just this month.

The ALRRM will exceed Mach 4 speeds, travelling at 3,069 miles per hour over 350 nautical miles, thanks to its air-breathing solid fuel ramjet (SFRJ) engine.

It would not require onboard oxidisers, allowing the missile to be lightweight and offer extended range compared to rocket-based weapon systems.

Ben Wolff, Palladyne AI CEO and president, said that according to the 2025 National Security Strategy, the US must build cost-effective missiles with high-performance strike capabilities.

The ALRRM will meet these requirements, per the company. It will be small and compact, yet it will accommodate a 150-lb warhead. It will also be compatible with fighter aircraft, especially the fifth-generation platforms.

Hypersonic systems travel at speeds more than the speed of sound, hence they face surface temperatures exceeding 1000 degrees Celsius.

Additionally, they are built using expensive materials, but the ALRRM will deliver the same performance at just a fraction of the cost.

This aligns with U.S defence priorities to balance cost without compromising on capability.

Since the missile will offer exceptional range, speed and payload while being compact, it is perfect for deep-strike missions in contested environments.
