WASHINGTON — Lockheed Martin has been chosen to build the U.S. Army’s new mid-range missile prototype, landing a nearly $340 million contract to take elements from naval missiles to forge the new weapon, the service’s Rapid Capabilities and Critical Technologies Office announced Nov. 6.

Through an other transaction authority agreement, Lockheed will take the Navy’s Raytheon-built SM-6 and Tomahawk missiles to put together a Mid-Range Capability, or MRC, prototype that consists of launchers, missiles and a battery operations center, according to an RCCTO statement.

A variant of the Tomahawk missile was used in a land-based cruise missile capability test last year. The SM-6 is a long-range, anti-air missile that has a surface mode.

This mid-range missile — expected to hit targets at distances beyond 500 kilometers — is to be fielded to an operational battery in fiscal 2023.

Defense News first broke the news that the Army was planning to field a mid-range missile capability designed to go after moving targets at land and at sea. The effort is meant to fill a gap in the service’s long-range precision fires portfolio in between the future Precision Strike Missile and hypersonic weapons capabilities.

The decision came out of a strategic fires study conducted earlier this year that identified the capability gap and the need to rapidly fill it. The RCCTO shortly after adopted the effort to rapidly field the new missile.

“Adapting existing systems as much as possible will allow us to move faster than traditional acquisition methods to get this capability into the hands of Soldiers in support of the National Defense Strategy,” Lt. Gen. L. Neil Thurgood, director of hypersonics, directed energy, space and rapid acquisition as well as the RCCTO chief, said in the statement.

“Soldier feedback and touchpoints will be embedded throughout the prototyping effort in order to make this system operationally effective the day it is delivered,” he added.

To meet the demanding timeline, the MRC prototype “will utilize and modify existing hardware and software from the Army and joint service partners and integrate additional technologies to achieve new operational effects,” the statement read.

The Army arrived at the decision to incorporate the SM-6 and Tomahawk missiles after a “broad review of joint service technologies potentially applicable to MRC,” according to the RCCTO.

To use the joint service technologies, the Army “will leverage Navy contract vehicles for missile procurement in support of the Army integration [other transaction authority] agreement,” the statement said.

“The capability also allows the Army and joint services to synchronize and leverage modernization efforts and investments across mid-range missile programs in support of multi-domain operations,” it added. “The MRC supports one of the Army’s chief roles in multi-domain operations: to use strategic fires to penetrate and disintegrate enemy layered defense systems, creating windows of opportunity for exploitation by the joint force.”

By 2023, the Army will have begun delivering a portfolio of strategic, mid-range and short-range fires capabilities that will change the paradigm against advanced adversaries Russia and China. The initial fielding of the Precision Strike Missile, capable of hitting targets out to 499 kilometers (with a likelihood of a greater range), will happen in 2023 as well as a ground-launched hypersonic missile.
