Raytheon (RTN) Secures Aegis Radar Transmitter Contract



Integrated Defense Systems division has won a contract from the U.S. Navy for the production of Aegis Weapon System AN/SPY-1D(V) Radar Transmitter Group, Missile Fire Control System MK 99 equipment, and associated engineering services. The contract is valued at $365.8 million. 

This contract has options which, if exercised, will bring the total contract value to $423 million. The contract falls under the Foreign Military Sales program that includes purchases for South Korea and Japan apart from purchases for the U.S. Navy. Work under this contract is expected to be completed by Oct 2022.

The SPY-1D(V) Transmitter and the MK 99 Fire Control System are an essential part of the Navy’s Aegis missile defense system. Over the past 35 years, these systems have been in continuous production and are in use aboard 108 warships worldwide, comprising 17 ships sailed by foreign nations.

The SPY-1D(V) is a high-powered radar transmitter that supports search, track and missile guidance functions, while the MK99 system communicates with the mission control station to identify and illuminate air targets.

Raytheon is one of the best-positioned, large-cap defense players and will continue to gain traction on the back of its strong fundamentals, focus on technological innovation and improvement of its product offering, which will ensure more contract wins and an enhanced growth trajectory.

The company has been enjoying a steady stream of contracts from several government establishments. As a result, total backlog at the end of the first quarter of 2016 was $34.8 billion, up from $32.5 billion at the end of the year-ago quarter.

The SPY-1D(V) radar system

The SPY-1D(V) radar upgrade is the newest improvement to the SPY-1D. The SPY-lD( V) littoral radar upgrade will supersede the SPY-1D in new-construction ships beginning in FY 1998, and will deploy in DDG 51 Flight IIA ships starting in approximately 2003. The third variant of this radar, known as the Littoral Warfare Radar, will improve the radar’s capability against low-altitude, reduced radar cross-section targets in heavy clutter environments and in the presence of intense electronic countermeasures. The SPY-1D radar system is the multi-function, phased-array, three-dimensional (range, altitude, and bearing) radar which conducts search, automatic detection, and tracking of air and surface targets. The SPY-1D also provides mid-course guidance for the SM-2 missile, and has also demonstrated a capability to track theater ballistic missiles. The AN/SPY-1D(V), under development for installation in some Flight IIA ships, is an improved system with better performance against targets in clutter, additional moving target indicator (MTI) waveforms, and greater ability to counter deceptive Electronic Attack measures. @fas.org

Mk 99 Missile Fire Control System

The Mk 99 MFCS controls the loading and arming of the selected weapon, launches the weapon, and provides terminal guidance for AAW (Anti-Air Warfare) missiles. It also controls the target illumination for the terminal guidance of SM-2.

The radar system associated with the Mk 99 MFCS is the missile illuminator AN/SPG-62.


AN/SPG-62 RADAR.-The AN/SPG-62 is I/J­Band fire control radar. The SPY-1 radar system detects and tracks targets and then points the SPG-62 toward the target, which in turn provides illumination for the terminal guidance of SM-2 missiles. Refer to chapter 1 for discussion on the different phases of missile guidance and the way radar is used for missile guidance. Remember that in order to track a target you need a very narrow beam of RF energy. The narrower the beam, the more accurately you can tell if you have one target or multiple targets (this is called radar resolution). This narrow beam radar is normally a second radar that works with a primary search or track radar. The AN/SPG-62 illuminating radar works as a second radar with the AN/SPY-1 series radar. 

In addition to the Mk 99 MFCS, the AEGIS SPY 1 series radar works with the Gun Fire Control System. @tpub.com
