In January 1977, the Navy introduced the first of its Improved Capability (ICAP) version Prowlers.

In 1984, the first ICAP II version of the EA-6B arrived. The Vikings introduced the AGM-88A High Speed Anti-Radiation Missile (HARM) to the EA-6B in 1986 and the Lancers (VAQ-131) were the first to successfully fire the AGM-88 from the EA-6B. In 1988 they introduced the new “Block 86” version of the ICAP II Prowler. During Operation Desert Storm, an updated HARM capability was introduced, which proved tremendously successful in the subsequent
