The GMARS solution proposed by the two companies – with the G denoting Germany – would be similar to HIMARS, but with a much larger chassis, provided by Rheinmetall, and a double loadout capability with two rocket pods instead of one, Bromberg said.
The chassis would be based on Rheinmetall’s protected, off-the-shelf HX 8x8 to maximize both parts’ commonality and interoperability with the existing, and growing, HX fleet, a Rheinmetall spokesperson said in a June 23 email. It would be built in Vienna and measure about 12 meters long, although the dimensions are still being finalized, they said. A HIMARS truck measures about 7 meters long.
Lockheed’s launcher-loader component would then be integrated onto the back of the truck, with overall integration efforts taking place in Germany.
“It’ll be our entrée into the European market with a European-produced version of rocket artillery … that can be offered throughout Europe,” Bromberg said.
Some components of the system would have to be procured from the United States through so-called combined foreign military sales and direct commercial sales, he noted. The Rheinmetall truck would be procured via direct commercial sale, he added.
The industry pair is also in conversation with German weapons maker Diehl for additional elements to be made locally, per Bromberg. “We’re in industry discussions right now about what can be produced or assembled in Europe, in terms of rockets,” he said.
Rheinmetall is interested in providing rocket motors, “which is a very viable option,” Bromberg said. Meanwhile, Diehl could provide some of the warheads along with Lockheed components. Those discussions haven’t ended yet, but Lockheed and Diehl are “well on our way to establishing what that relation is,” he noted.
Once under contract, the initial five GMARS systems could be delivered for testing and acceptance as early as 2025. “Then, if the Germans wanted to have additional capability in the interim, they could request from the U.S. government to buy straight HIMARS, and then use that for a stopgap,” Bromberg said.
Rheinmetall could have the chassis ready for integration within months of a contract signature, the company spokesperson said.
Should Germany choose to support its production, GMARS will feature about 80 percent commonality with the HIMARS munitions packages and logistics chain, Bromberg noted. It will require three personnel to operate, the same as HIMARS.
“We know that our HIMARS munitions will fire off anything GMARS that we do with Rheinmetall,” Bromberg said. “We know Germany has already been approved to fire these rockets on their older systems. So this will be a natural transition, as we present a new launcher to fire our munitions.”
