＞Look to Japan to Solve the US Navy’s ASM Crisis
＞The U.S. Navy’s traditional blue-water advantage in the Asia-Pacific is at risk. Japan can help.

What these missiles have in survivability and range, however, they lack in speed.
Compared to the Chinese and Russian missiles, the LRASM and Tomahawk are only capable of subsonic operation.
This is precisely why the Navy should, in addition to procuring the LRASM/Tomahawk,
move to collaborate with Mitsubishi Heavy Industries (MHI) and the Japanese Ministry of Defense, the developers of the XASM-3.

Procuring the XASM-3 is a tactical no-brainer for the Navy. Like the LRASM, it is a stealthy missile, yet unlike its American counterparts,
its ramjet engine allows it to reach speeds in excess of Mach 3.
This combination of speed and low-observability may prove decisive in a future A2/AD conflict,
as the XASM-3 would be able to both evade sensors and outrun legacy defensive systems.
Deployment with stealthy aircraft like the F-35 or B-2 would help mitigate its relatively short range of ~90 nm,
but co-development between the U.S. and Japan on the missile’s propulsion could conceivably overcome this hurdle and also allow for ship-based deployment.
Even at its current stage, the combination of ship-based LRASM and stealth aircraft-based XASM-3 deployment would represent an devastating fielding of stealth ASM capabilities.
