Swordfish was the fifth and last U.S. underwater test. It was a DOD sponsored full scale test of the ASROC anti-submarine rocket weapon system. The ASROC used the LASL developed W-44 warhead (similar to that tested in Nougat Chena), which had a nominal yield of 10 kt. This shot had a number of objectives:

It was a weapons effects test to evaluate how it would affect U.S. ships, submarines, and sonar systems in the area (a target array of four destroyers and a surfaced submarine were positioned at distances between 2200 and 4600 yards from surface zero);
It was a safety test to evaluate the radiation hazard to the launching vessel;
It was a proof firing of the ASROC by a regular Navy crew under simulated wartime conditions.
The ASROC was fired from the destroyer USS Agerholm (DD-826) at a target raft 4348 yards away. The rocket missed its sub-surface zero point by 20 yards and exploded 40 seconds later at a depth of 650 feet in water that was 17,140 feet deep.
