WELCOME TO THE USMC SIKORSKY HRS DATABASE HOMEPAGE
H (helicopter) R (transport) S (Sikorsky)
The goal is a complete database for all 250 HRS-1, -2, and -3 helicopters. Most served multiple Marine and Navy squadrons during their careers and wore many different markings. These pages (link on left) contain hundreds of photographs of HRS's in operation with the USMC, USN, USCG, foreign forces, and in civilian use. Eleven transport squadrons operated the HRS:
HMR-161, -162, -163, -261, -262, -263, -361, -362, -363, HMX-1 and HMR(L)-264 .
Compiling this data can only be done through photographs, personal logbook entries, and personal recall. Can you help? If so, please email the webmaster via the link on the left.
