Patriot TMD

Patriot can be transported worldwide via C5 cargo plane. Built in diagnostic software; the computer tells you what's wrong with the system, making maintenance and repair much easier. Patriot battalions can interface with Hawk battalions and with the Air Force AWACS.

Patriot-unique equipment at the Headquarters and Headquarters Battery (HHB) includes the information and coordination central (ICC), communications relay groups (CRGs), antenna mast groups (AMGs), trailer mounted electric power units (EPUs), and guided missile transporters (GMT). The Patriot firing battery equipment includes the AMG, radar set (RS), engagement control station (ECS), truck mounted electric power plant (EPP), and up to sixteen launching stations (LSs). Both the battalion and firing batteries are equipped with a semitrailer maintenance center.

Testing of Patriot's response to a unique, advanced electronic countermeasure (ECM) technique exposed an air defense system weakness and recommended corrective measurees. Over 155 Patriot surveillance investigations and 6 missile firings were completed in extensive ECM environments consisting of stand-off jamming, selfscreening jamming, and chaff.

In February 1995, the U.S. Army took delivery of the first PATRIOT Advanced Capability-2 (PAC-2) Guidance Enhanced Missile (GEM). The GEM incorporates improvements to the front end of the PAC-2 missile receiver to enhance its effectiveness and lethality against SCUD-class ballistic missiles. The U.S. Army will field about 350 PAC-2 GEM missiles.

Patriot Advanced Capability-3 (PAC-3)

Patriot Advanced Capability-3 (PAC-3) is a high/medium advanced surface-to-air guided missile air defense system. PAC-3 is a major upgrade to the Patriot system. The PAC-3 Operational Requirements Document (ORD) represents the Army Air Defense need to buy back required battlespace lost against the current and evolving tactical missile and air breathing threat. PAC-3 is needed to counter/defeat/destroy the 2008 threat and to extend Patriot's capabilities to accomplish new/revised missions.

The PAC-3 Program consists of two interrelated acquisition programs - The PAC-3 Growth Program and the PAC-3 Missile Program. The Growth program consists of integrated, complementary improvements that will be implemented by a series of phased, incrementally fielded material changes. The PAC-3 Missile program is a key component of the overall improvements of the Patriot system, it will provide essential increases in battlespace, accuracy, and kill potential.

PAC-3 is a much more capable derivative of the PAC-2/GEM system in terms of both coverage and lethality. The PAC-3 has a new interceptor missile with a different kill mechanism--rather than having an exploding warhead, it is a hit-to-kill system. The PAC-3 missile is a smaller and highly efficient missile. The canister is approximately the same size as a PAC-2 canister but contains four missiles and tubes instead of a single round. Selected Patriot launching stations will be modified to accept PAC-3 canisters.

The Battalion Tactical Operations Center (BTOC) is an M900 series 5-ton expandable van that has been modified by the addition of data processing and display equipment, and utilized by the battalion staff to command and control the Patriot battalion. The BTOC allows the staff to perform automated tactical planning, communications link planning, and to display situational awareness information.

In the 1997 budget DOD added about $230 million for the PAC-3 through the Future Years Defense Program (FYDP) and established a realistic schedule to lower the program execution risk by extending the engineering and manufacturing development (EMD) phase of the program by ten months. System performance will be improved by re-phasing the missile and radar procurements; upgrading three launchers per battery with Enhanced Launcher Electronics Systems; and extending the battery’s remote launch capability. PAC-3 Low-Rate Initial Production (LRIP) will begin in the second quarter of fiscal year 1998, and the First Unit Equipped (FUE) date is planned for the fourth quarter of fiscal year 1999. The FUE capability will consist of 16 missiles and five radars which will be placed in one battalion. As of 1996, in addition to funds being programmed for the Ballistic Missile Defense Organization, the Army planned to spend $9.6 billion for all planned purchases of Patriot missiles, $490 million for modifications and $335 million for product improvements.
