The second iteration of HS-7 was established on 15 December 1969, and at the time the squadron reported having 4 Sikorsky SH-3D Sea Kings, out of an allowance of 8, on hand. They were home-ported at NAS Quonset Point, Rhode Island.
(1) For much of HS-7's history this was the official squadron insignia. It was approved on 24 April 1970. It contains elements that expound on the squadron and its mission. The carrier in the background indicates that HS-7, for much of its history, was carrier-based. The helicopter employs a dipping sonar, a sensor that for the most part, was only used on helicopters in the HS community. Of course, the enemy (Soviet) submarine - protecting the carrier against the Soviet submarine threat was HS-7's primary mission. The lightning bolts represent the engagement of the submarine, while the seven stars indicate the squadron's designation. The use of the color green is a nod to HS-7's nickname - The Shamrocks.
