AGM-78 Standard ARM. That new weapon allowed launches from significantly longer range with a much easier attack profile, as the Standard could be launched up to 180 degrees off target and still expect a hit and its speed allowed it to travel faster than the SA-2. Even after the Standard missile entered service, the Weasels still carried the Shrike because the Standard cost about $200,000, while a Shrike cost only $7,000. If USAF pilots expended a Standard they would have to fill out a lengthy form during debriefing. A somewhat standard load for the F-105G was a 650 US gal (2,500 L) centerline fuel tank, two Standards on inboard pylons and two Shrikes on the outboard pylons.

Variants

There are many subvariants, each tuned to a different radar band.
Angle gating, used to prioritize targets, was included in every subvariant of the AGM-45A and B after the A-2 and B-2. It was also slow and the lack of punch in the warhead made it difficult for
bomb damage assessment, as well as inflicting any damage to the Fan Song Radar vans beyond a shattered radar dish, an easy item to replace or repair. The short range, combined with its lack of speed (compared to the SA-2 SAM) made for a difficult attack. The missile had to be well within the range of the SAM radar and if a SAM was fired the SAM would get to the aircraft first. Also the missile had few tolerances and had to be launched no more than + or − 3 degrees from the target. Many pilots in Vietnam did not like the Shrike because of its limitations and its success rate of around 25%.
The differences between the AGM-45A and B are in the rocket motor used, and in the warheads capable of being fitted. The AGM-45A used the

As for warheads, the Mk 5 Mod 0, Mk 86 Mod 0, and WAU-8/B could all be fitted to the AGM-45A and were all blast-fragmentation in nature. The AGM-45B made use of the improved Mk 5 Mod 1 and Mk 86 Mod 1 warheads, as well as, the WAU-9/B, again all blast-fragmentation in type.
