The US Air Force modified the GBU-31 JDAM bomb. Now it is suitable for striking moving and static targets at sea. The military has already tested it in action. In terms of power, it is comparable to a torpedo.
While a single torpedo from a submarine can easily destroy an entire ship, its use is not always desirable. For example, the launch gives the enemy the location of the submarine. To solve the problem, the US military is developing a cheap analogue that will replace torpedoes, but will not be inferior to them in efficiency.
The US Air Force has already modified the GBU-31 JDAM bomb weighing 907 kg for strikes against moving and static naval targets. However, the military does not disclose exactly how they did it. In the public domain, there is only information about the tests of the modified torpedo bomb. It is reported that three F-15E Strike Eagles from the 85th Test and Evaluation Squadron supported the tests as part of the QUICKSINK joint capabilities technology demonstration on August 26, 2021.
