To counter Russia’s electronic warfare battalions, the Army wants to field a revolutionary EW weapon by 2023. But how do they get there?

The US Army can’t match Russia’s battalions of powerful radio jammers. Instead, it’s trying to build a nimble high-tech David to defeat the EW Goliath.

The test was a big achievement for two much-criticized programs: the Joint Strike Fighter and the Army’s IBCS network — and for the services’ struggle to work better together in a future war.

The Army’s experimental Multi-Domain Task Force tested new tactics for Pacific conflict, hand-in-glove with the Marines, Air Force, and Australians.

The battery of eight missiles, while primarily meant to test out tactics, will be capable of combat. So will a prototype battery of lasers entering service in 2021.

“You want to kill a swarm of things — whatever that thing is — lasers are not really a swarm-killing tool. They can kill things fast, but they can’t kill a swarm of things fast enough.”

The Army can cope with regional dangers like Iran even as it refocuses on Russia and China, the secretary said. In fact, he said, the Army’s controversial modernization program will help with both sets of threats.

The Marines are hellbent on fielding the troubled CH-53K helicopter to supply the far-flung island outposts they plan on using against China.

The sea services have their own space specialists, but those personnel don’t only work on space — so who stays and who goes?

A light scout and a mid-size transport remain Army aviation’s top two priorities, Secretary Mark Esper said, but industry needs to start thinking about the next heavy-lift aircraft and stop fighting against cuts to the venerable CH-47.
