Bath Iron Works plans called for delivery to occur 9 August 1985, but that date slipped due to an extended strike at BIW that began 30 June 1985.
Escaping propellant combustion products cut into the craft's solid rocket booster, however, and 73 seconds after launch a massive explosion destroyed Challenger, killing all seven astronauts on board.
Simpson took part in the ensuing search and rescue effort, and subsequently received the Coast Guard Unit Commendation with Operational "O" for her participation.
[5] Beginning January 1988, Simpson's first overseas deployment was to the Persian Gulf as part of Operation Earnest Will, to escort reflagged Kuwaiti oil tankers during the Iran–Iraq War.
On 18 April, Simpson, along with Wainwright and Bagley, destroyed Iranian naval and intelligence facilities on the oil platform Sirri in the Persian Gulf.
20 February 1990, Simpson rescued 22 crew members from Surf City, a reflagged Kuwaiti tanker carrying $9 million in naphtha and gas oil.
Surf City was transiting near the Iranian island of Abu Musa when it exploded, killing two and forcing the crew to abandon ship.
According to Central Command, Simpson was not escorting the tanker, but was monitoring its progress from 3 nautical miles (5.6 km) away and responded immediately to rescue the crew.
[10] In November 1995, Simpson deployed to the Mediterranean joining the United States Sixth Fleet NATO's Standing Naval Force Atlantic.
[17][18] On 17 January 2012, Simpson deployed to the Sixth Fleet Area of Responsibility, participating in Africa Partnership Station 2012, and Operation Active Endeavor.
Ports of call included Funchal, Rota, Casablanca, Dakar, Lagos, Accra, Mindelo, Souda Bay, Sicily, Naples and Praia.
[23] When Simpson was decommissioned, it meant the last United States ship still in active service to have sunk an enemy vessel was the 217-year-old USS Constitution.
