Summary
The U.S. Navy is developing the Silent Anvil Air-Launched Torpedo, a compact, stealthy anti-submarine weapon designed for unmanned aircraft. This innovative torpedo, weighing under 268 pounds and fitting standard bomb racks, aims to revolutionize undersea warfare by enabling a wide array of drones and aircraft, like the MQ-9 Reaper, to conduct anti-submarine operations. This initiative, driven by concerns over growing Chinese naval power, could significantly shift anti-ship warfare to the aerial domain, potentially reducing reliance on specialized ASW aircraft and alleviating shipbuilding pressures. The SAA-LT’s low detection profile promises to enhance stealth capabilities, fundamentally altering how submarines are tracked and targeted.

The U.S. Naval Air Systems Command seeks to develop a small anti-submarine weapon that unmanned aircraft systems can fire after taking off from carriers or other vessels at sea.
A request for information released by the service
A request for information released by the service this month has specified that the new weapon, known as the Silent Anvil Air-Launched Torpedo or SAA-LT, will be designed at a smaller scale than most torpedoes at 70 inches long and weigh no more than 268 pounds.
The Navy also wants the Silent Anvil to easily fit in the BRU-61/A bomb rack, which fits on a wide array of fighter jets, bomber aircraft and also on unmanned aircraft systems. The bomb rack is typically used to carry precision-guided glide bombs known as GBU-39Bs, which have a nearly equivalent weight to the planned Silent Anvil torpedo.
A key component of the Navy’s desired design is stealth. The Silent Anvil is intended to approach and strike underwater targets with an extremely low detection profile.
This new weapons development thus has the potential
This new weapons development thus has the potential to upend the status quo of undersea warfare considerably.
Until now, the Navy’s primary aircraft designed for anti-submarine warfare has been the P-8A Poseidon manufactured by Boeing, which is designed to hunt submarines and is armed with torpedoes and cruise missiles.
The development of the Silent Anvil comes during a time when growing Chinese naval powerhas been athe Arctic and Pacific regions
If the Navy succeeds in shrinking ship-killing munitions
If the Navy succeeds in shrinking ship-killing munitions to the size of small bombs, it could relieve pressure on the service to make immediate gains in shipbuilding as anti-ship warfare would shift significantly to the aerial domain.
Enhancing unmanned aircraft systems platforms with torpedoes could potentially reduce strain on human service members and open new AI-enhanced possibilities for tracking and targeting submarines.
The world witnessed the devastating effect of a torpedo when the U.S. Navy sunk the Iranian warship IRIS Dena using a Mark 48 on March 4. The same level of firepower now stands to be condensed and fielded by unmanned aerial platforms.
Will weapons like the Silent Anvil make submarines less relevant over time? If development of this new air-delivered torpedo proves successful, it has potential to shape not only sea warfare but how the world has perceived best practices for maintaining undersea nuclear deterrents.
