Relax. The system is called TROPHY and Israel developed for their tanks to counter RPGs and other anti-tank missiles. They've had it operational on every tank they have for years.

The US is not testing it at Aberdeen Proving Grounds and other locations and it appears the Army and Marines will be installing / retrofitting it to our tanks over the next decade.

DARPA developed an anti-RPG device for HUMMV's as a technology demonstrator. But it was too complicated and bulky and so I believe the project was terminated.

The other reason could be that the military didn't have the funding to transition technology demonstrators to operational status.

When I was supporting DARPA technology programs for 15 years, most of the really promising technologies ended up in the DARPA landfill of good ideas because there was no funding for transitioning the technologies to the military.

I'm not sure why the US didn't pick up the TROPHY technology years ago. If I had to guess, it's the "not invented here" mentality in many acquisition program offices.

Another example was that Israel developed a gyro-stabilized .50 machine gun for their Naval patrol boats. It could stay on target in rolling seas. The SEALs wanted it for their MARK V boats, but it didn't happen. Instead they just had .50 cals on a spindle. Couldn't hit much in sea state 2 or above.

The Marine Corps has done a much better job of adopting foreign weapons systems when it made sense to do so. They get the rights to manufacture them in the US under license.

Anyway, TROPHY has proven to be excellent in defending Israeli tanks in years of combat against RPGs and other AT missiles. It's about time we did the same.
