Lindsey Heflin In April, an F-15 sunk a ship in the Gulf of Mexico with a modified 2,000-pound GBU-31 Joint Direct Attack Munition. The new bomb variant, dubbed Quicksink, is intended to provide the Air Force with a torpedo-like anti-ship smart weapon. The US Air Force Research Laboratory (AFRL) and Eglin Air Force Base's Integrated Test Team recently demonstrated a new low-cost, air-delivered smart weapon capability intended to defeat maritime threats.The test, which happened on April 28, 2022, saw an F-15E Strike Eagle releasing a modified 2,000-pound GBU-31 Joint Direct Attack Munition (JDAM) and successfully destroying a full-scale surface vessel in the Gulf of Mexico.This test is the second experiment in the Quicksink Joint Capability Technology Demonstration, a collaborative effort with AFRL, the 780th Test Squadron of the 96th Test Wing, and the 85th Test and Evaluation Squadron of the 53rd Wing, and funded by the Office of the Under Secretary of Defense for Research and Engineering."Quicksink is an answer to an urgent need to neutralize maritime threats to freedom around the world," said Col.
