RIM-66A
Original Standard missile to enter service in 1967. Block IV was the main production introduced in 1968. Blocks I to III being prototypes and low rate production. Many block III upgraded to Block IV standard by adding ECCM improvements. Using the older Mk 27 rocket motor of the RIM-24C Tartar the RIM-66A is shorter than all other Standard missiles.
RIM-66B
Improved design with higher reliability. Also known as Standard Block V. Improvements include a much larger MK 56 dual thrust rocket motor, new blast fragmentation warhead with proximity fuse and improved autopilot. Produced new and many RIM-66A were converted to B standard.
RIM-66E
Final SM-1MR version that was created by adding components developed for the SM-2, such as the new seeker. The RIM-66E consists of many subvariants. These include Block VI with MK 45 Mod 4 proximity fuse. These come with original MK 90 (RIM-66E-1 and E-7) or improved MK 115 warhead (RIM-66E-3 and E-8). The RIM-66E-5 Block VIA and RIM-66E-6 Block VIB both feature the MK 115 warhead, but have respectively have the MK 45 Mod 6 and Mod 7 fuse with improved performance against low RCS targets.
