MIM-104A Patriot

Start of Service: 1984

Notes: Warhead fragments weigh 2 g.

MIM-104B Patriot SOJC

Notes: Adds surface-to-surface capability against ground based radar jammers. The missile flies a lofted trajectory towards the jammer and selects the strongest jammer to kill. Retains same AAW capability as MIM-104A.

MIM-104A/B Patriot PAC-1

Start of Service: July 1988

Notes: Provided an interim ATBM capability, via software changes to radar search/track algorithms and hardware changes to allow the phased array radar to elevate to nearly 90° (previously it was 45°). The missile was unchanged. First test was in September 1986 against a MGM-52 Lance target.

MIM-104C Patriot PAC-2

Start of Service: Late 1990

Notes: Purpose-built ATBM missile. Further software changes were made in the PATRIOT complex, and a new blast/fragmentation warhead with much larger fragments (45 g vs the old one's 2 g); in addition to a new Fuze designed for high velocity closing targets such as missiles. First test was in November 1987 against another PATRIOT missile.

MIM-104D Patriot PAC-2/GEM

Start of Service: 1995

Notes: Improved MIM-104C with better seeker and fuze for better performance against low-RCS targets, or those with extremely high closing rates (ballistic missiles).

MIM-104E Patriot PAC-2/GEM+

Start of Service: November 2002

Notes: Improved MIM-104D with a new seeker and fuze for even better performance against low-RCS targets or high closing rate targets (ballistic missiles). Older components dating from the 1980s were replaced with modern ones to improve reliability. Saw combat in the opening phases of the 2003 Iraq War.
