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.

WHY THE INTEREST?
 
My father, Roy N. Thorson, was a PBJ (B-25) pilot during WWII. When recalled for Korea in April 1951 he volunteered for helicopter training and became the 523rd Naval helicopter pilot. He flew the HRS at Marine Corps Air Facility, Santa Ana, California with HMR-162, MAMS-16, and HMR-163 until April 1953. These Marines were a unique breed of pioneers; testing and proving the tactic of vertical envelopment and operations from aircraft carriers.  This site is dedicated to them.
