    I like the USAF UH-1F/P (The "P" designation applies to the armed version) models quite a bit, as they are not quite the run-of-the-mill Hueys, as it is a blend of features from both the short- and long-fuselage members of the UH-1 family. The T-58 engine mount is distinctive and much the Agusta-Bell AB-204B, which was fitted with a Rolls-Royce Gnome turboshaft, itself a license built T-58.

    Some corrections, additonal infos and photos.

    The 21st Special Operations Squadron (SOS) operated CH-3E/HH-3E helicopters from Nakhon Phanom Air Base (NKP), Thailand. It first was tasked with placing electonic sensors in Laos and around the "McNamara Line". After this operations became to dangerous for slow flying helicopters the squadron was tasked to support the MACVSOG Prairie Fire/Shining Brass missions.

    The 20th SOS “Pony Express” flew H-3Es from Udorn RTAFB, Thailand on missions into Laos and North Vietnam.

    The 20th SOS "Green Hornets" flew UH-1F/Ps from Nha Trang, RVN and supported SOG operations in Cambodia.

    The 40th Aerospace Rescue and Recovery Service (ARRS) flew HH-53B/Cs on rescue missions from Udorn and Ubon, Thailand.

    The 38th and 39th ARRS operated HH-43Bs from various air fields around the country (Plei Ku, Nha Trang, Bien Hoa, Phan Rang, Binh Tuy etc.).

    CH-3E/HH-3E Jolly Green Giant:

    The diffrence between the CH and HH designation is simply that the HH version had a refueling probe while the CH didn't.



    A CH-3E at Nakhon Phanom, Thailand.



    Two CH-3Es above South East Asia (SEA). The one in the back is still in its factory painting.



    Two "Jollys" over SEA.



    A CH-3E pics up a team after a mission.



    A HH-3E refueling somewhere over SEA via an MC-130.



    A crew member prepares himself for dropping an ADSID (Air Delivered Seismic Intrusion Detector) off the sidedoor of a CH-3E.



    The H-3s were capable of landing on water like the H-53s, too.




    The H-3Es and the "TAT":

    A more unknown but interesting feature for the H-3Es was the so called "TAT" (Tactical Armament Turret 102B) which was a pod equipped with a turret mounted M134 minigun and a 8.000 round magazine. The weapons were controlled by crewmembers from the back of the helicopter via door/window mounted electro-optical sights. The system could be mounted instead of the external fueltanks but if the decision came up the pilots mostly selected the extra fuel above extra firepower.

    A TAT mounted under the right sponson of a H-3E.



    The TAT in action. It had a selectable firerate of 2.000 or 4.000 rpm.

    Hehe, no problem. They're of course an interesting peace of technique. I guess they're somehow based on the turret of the Cobra but didn't found any proof.

    Anyways, I always wondered why something like this isn't available for H-53s. Such pods could be helpfull toys I guess.

    That's not "factory painting" but the famous Black Mariah CH-3E #6309676 of the 20th Helicopter Squadron. Initially painted black for secretive night-missions over SEA. Now on display at the National Museum of the United States Air Force:

    Ok, I see. I thought it was an early picture and it simply didn't got the SOS painting. Thanks for the info!

    Since the TAT turrets were all made by Emerson Electric... And yes, early Cobras (with the single minigun) had the TAT-102.
    Also the Navy tried mounting the same pods on their HH-3A and the turret on the HH-2C CSAR choppers.

    I know that there were a couple of systems available that were designated as "TAT". There was a "Mini-TAT" for the Kiowa for example but I didn't knew about these "turret-pods" for the H-3s.

    Btw, I also just stumbled about some interesting HH-2 photos.



    Interesting config with four M60s in a double nose-turret.



    Even more interesting that this was an Army evaluation.



    But that's maybe worth an own thread.

    Thanks for the pics. I had the last one, but (much) smaller.
