Navy asks Raytheon to build ESSM Block 2 anti-aircraft shipboard missiles in potential $1.3 billion deal

WASHINGTON- Missile experts from Raytheon Technologies Corp. will build next-generation shipborne missiles capable of defeating a wide variety of aircraft and missile threats over two years with an active radar seeker that can operate independently of the launcher in a potential $1.3 billion contract dollars announced Thursday.

U.S. Naval Sea Systems Command officials in Washington are requesting full-rate production of the RIM-162 Evolved Seasparrow Missile (ESSM) Block 2 2021-2023 from the Raytheon Missiles & Defense Segment in Tucson, Arizona. The initial contract value is $358 million. With options, the contract could reach nearly $1.3 billion over the next six years.

ESSM Block 2 was first deployed with the Navy and allied navies last year. It is a ship-based self-defense missile with a dual-mode X-band radar seeker that can engage enemy aircraft and missiles at ranges over 25 miles. RIM stands for radar intercept missile.

Compared to its predecessor ESSM Block 1, the ESSM Block 2 has increased maneuverability and other improvements that allow the missile to defeat future threats against US and allied navies operating in hostile environments, according to Raytheon officials. The ESSM Block 2 active seeker will support terminal engagement without the launcher’s target illumination radars.

In addition to the US Navy, the governments of Australia, Belgium, Canada, Denmark, Germany, Greece, the Netherlands, Norway, Portugal, Spain and Turkey will operate the anti-missile missile. -aircraft ESSM Block 2.

The ESSM is a medium-range, semi-active homing missile that performs flight corrections via radar and mid-course data uplinks. The missile provides a reliable self-defense capability against agile, high-speed, low-altitude anti-ship cruise missiles, low-speed airborne 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 connect to an 8-inch-diameter guidance section with a radome-protected antenna for semi-active guidance and a warhead. It features a high-thrust solid propellant rocket motor and tail control via a thrust vector controller.
