Navy taps RTX Raytheon for ESSM Block 2 radar-guided air-defense shipboard missiles in $525.5 million deal
WASHINGTON – Missile experts at RTX Corp. will build next-generation radar-guided shipboard missiles able to defeat a wide variety of aircraft and missile threats under terms of a half-billion-dollar contract announced in September.
Officials of the U.S. Naval Sea Systems Command in Washington are asking the RTX Raytheon segment in Tucson, Ariz., for RIM-162 Evolved Seasparrow Missile (ESSM) Block 2, which uses an active radar seeker than can operate independently of the launch ship.
The contract's initial value is $525.5 million. With options the contract could reach nearly $2.2 billion over the next six years.
The ESSM Block 2 shipboard missiles first were deployed with the Navy and allied navies in 2020. It is a ship self-defense missile with a dual-mode X-band radar seeker than can engage enemy planes and missiles at ranges beyond 25 miles. RIM stands for radar intercept missile.
Compared with its ESSM Block 1 predecessor, the ESSM Block 2 air-defense missile has increased maneuverability and other enhancements that enable the missile to defeat future threats to U.S. and allied navies operating in hostile environments, Raytheon officials say. The ESSM Block 2’s active seeker will support terminal engagement without the launch ship’s target illumination radars.
In addition to the U.S. Navy, the governments of Australia, Belgium, Canada, Denmark, Germany, Greece, The Netherlands, Norway, Portugal, Spain, and Turkey will operate ESSM Block 2 anti-air missile.
ESSM is a medium-range, semi-active homing missile that makes flight corrections via radar and midcourse data uplinks. The missile provides reliable ship self-defense capability against agile, high-speed, low-altitude anti-ship cruise missiles, low velocity air threats like helicopters, and high-speed, maneuverable surface threats.
The missile is 12 feet long and has 10-inch-diameter control and rocket motor sections that tapper to an 8-inch-diameter guidance section with a radome-protected antenna for semi-active homing and a warhead. It has a high-thrust, solid-propellant rocket motor and tail control via a thrust vector controller.
The first production ESSM Block 1 was delivered in late 2002 and has been in full operational use in the U.S. since 2004.
Raytheon will do the work on this contract in Tucson, Ariz.; Edinburgh and Eight Mile Plains, Australia; San Jose, Torrance, and Westlake Village, Calif.; Mississauga and Cambridge, Ontario; Ottobrunn, Germany; Nashua, N.H.; Andover, Mass.; Koropi Attica, Greece; Canton, N.Y.; Grenaa, Denmark; Aranjuez, Spain; Camden, Ark.; Milwaukie, Ore.; and other locations, and should be finished by September 2030.
