Helicopter Sea Combat Squadron 2 (HELSEACOMBATRON 2 or HSC-2) (previously Helicopter Combat Support Squadron 2 (HC-2)), also known as the "Fleet Angels" (previously the "Circuit Riders"), is a helicopter squadron of the United States Navy based at Naval Station Norfolk operating the Sikorsky MH-60S Seahawk.

HSC-2 was established as the second squadron designated Helicopter Combat Support Squadron TWO (HC-2) on 1 April 1987 from components of several helicopter squadrons, specifically; HC-6's Atlantic Fleet VIP det flying the VH-3A Sea King, HM-12's Vertical Onboard Delivery (VOD) det flying the CH-53E Super Stallion, and HS-1's Sea Det flying the SH-3G Sea King in support of the Commander U.S. 6th Fleet in Gaeta Italy and the Commander Middle East Force (what would eventually become 5th Fleet) in Manama Bahrain.

[2] HC-2 provided detachments to the Persian Gulf in 1990 and 1991 in support of Operations Desert Shield and Desert Storm, conducting search and rescue, medical evacuation, and prisoner transportation flights, as well as assisting in the search for naval mines and providing other assistance to the fleet.

Civilian assistance was rendered in the aftermath of Hurricanes Dennis and Floyd during which two members of the squadron would be awarded the Navy and Marine Corps Medal for their heroism in rescuing stranded people in North Carolina.

Unit citations received over the years have included both a Battle Efficiency Award and a Meritorious Unit Commendation as well as the Chief of Naval Operations Aviation Safety Award in honor of more than 60,000 flight hours without an accident.
