WELCOME TO THE USMC SIKORSKY HRS DATABASE HOMEPAGE
H (helicopter) R (transport) S (Sikorsky)
The goal is to compile a comprehensive database for all 250 USMC HRS-1, HRS-2, and HRS-3 helicopters.
Most HRS's were assigned to many Marine and Navy squadrons during their careers and therefore had many different markings. The database pages (link on left) currently contain hundreds of photographs of HRS's in operation with the USMC, USN, USCG, foreign forces, and in civilian use. Eleven Marine 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 through personal recall. Can you help? If so, please email the webmaster via the link on the left.
