  1. When MAG 16 was at Phu Bai they did not have PSP (Pierced Steel Planking) although they did have revetments and despite peneprime sprayed surfaces (tar sprayed dirt and rock to reduce brown outs resulting from aggregate dust and to limit FOD) they still had fairly dirty skids since you got the kit to practice weathering techniques. You can see some good amounts of fouling and wear on these slides including spilled fuel. This is before MAG 16 moved to Marble Mountain Air Field MMAF outside of Da Nang. The last slide here shows how dirty the tail became with soot from the exhaust. If you want to skip Vietnam and go with Kit decal options here's your Huckleberry @ NAS Glenview, Illinois 2 AUG 1974. If you need Hi-Res I have these in original format which is 1600x1800.
  2. Those are called Dynamic Stops In Short 4th not shown in your image fully engaged in flight. 3rd position as you have them is closer to lower rotor RPM as indicated by the image of the crew member clearing the FOD intake filter and the 3rd position in the take off image. Final image you cant even see them as they are bucked up against the underside of the 540 rotor head. Note the pitch of the blades in the last two images is the same but the rotor RPM is likely still coming up on the image of them nose low and moving towards ETL Effective Translational Lift.
  3. Just cast your figures after you sculpt them and use non-sulfuric clay or better yet resin. Most polymer clays have sulfur and will also melt plastic on kits. I made that mistake building B pillars and the overhead console. Any new updates?
  4. From Combat After Action Report - Airmobile Operations in Support of Operation Lam Son 719 (101st Airborne Division February 1971 thru 6 April 1971 dated 26 July 1971 "Throughout the operational area the NVA deployed an extensive, well-integrated, highly mobile air defense system which included large numbers of antiaircraft weapons of several calibers, the basic weapon being the 12.7mm machine gun. (Figure 1-7) Some antiaircraft weapons were apparently radar-controlled. " From 101st Airborne Division (Airmbole) Final Report Airmobile Operations in Support of Operation Lam Son 719 8 Feb - 6 Apr 1971 dated 1 May 1971 Camp Eagle, RVN Antiaircraft Engagements "In all cases where antiaircraft weapons were encountered, the 2/17 Cav requested TAC air, since the USAF has the standoff range and the fire power to engage AA weapons at a more acceptable risk level than does the Cav with organic gunships. When the Air Force had higher priority missions and was not available for such support 'organic aircraft on occasion engaged and destroyed AA weapons as large as 37mm. However, 23mm and larger were usually not engaged but marked for a FAC. AA engagements tactics varied from troop to troop, but generally the concept was to us as many gunships as possible, attacking simultaneously from different directions. If, as in the first month, OH-6A's were with the team, they were put in orbit out of effective range until the gun was destroyed. The most difficult aspect of engaging NVA AA weapons was to pinpoint the exact location of the weapon. The NVA had excellent fire discipline and used mutually supporting positions. Once a weapon was pinpointed, the AH-1G had a range standoff advantage over the 12.7mm and 14.5mm. Flechettes, HE and WP rockets and the XM-35 20mm gun if available were all used in engagement. The most significant AA threat faced by the Cav was the 12.7mm heavy machine gun. The NVA employed large numbers of these weapons, and located them so as to be mutually supporting along the helicopter approach routes. As far as can be determined the Cav lost no aircraft to weapons larger than 12.7mm, although several hits were recorded from 37mm airbursts. To counter the 12.7mm threat and still not become unacceptably vulnerable to larger caliber fire, most Cav teams operated at 3500 feet AGL to 5000 feet AGL, except for one AH-1G operating low and fast to detect targets." Also add 57mm and SA-7 missiles.
  5. You're welcome. I wouldn't bet that the report no longer exists. In fact I am sure it's out there. Plenty of information I uncovered in my research into SEANITEOPS existed in multiple places and required a declassification request as well. There are doctorate papers on DTIC that reference the report you are after for those specific systems. You will just need to dig harder. The link I sent is a path forward with some chronology as well as 3 possible HUMINT sources to search out. Are you only looking at US DoD programs? Only reason I ask is because another avenue is the Spanish Navy Fleet Air Army as they flew the Hughes500ASW from the Dedalo R.01 aircraft carrier (former USS Cabot CVL-28) and more typically from the destroyer Blas de Lezo. The Spanish 6a Escuadrilla was commissioned in 1972 with the Hughes 500ASW, thirteen initially with 11 still in service in 1982. They carried 2 Mk44 or 46 torpedoes, only 1 torpedo was carried when equipped with the AN/ASQ-81 MAD (Magnetic Anomaly Detector). They were also capable of carrying a 7.62 minigun on their port side and in the early 80s were slated to replace the AB-47s in the Naval Fleet Air Army.
  6. What you are after was conducted by NADC According to "History of the Naval Air Development Center" documentation at DTIC. According to this document there were recorded interviews Tape 13 specifically with Richard James among others, pg 53-54. If anything this is a useful index for it's timeline. https://apps.dtic.mil/dtic/tr/fulltext/u2/a123645.pdf DTIC does in fact have quite a large number of Navy documents and more controlled documentation if you have a CAC card. NADC was permanently closed in the 90s as part of BRAC. It was moved to NAS Patuxent River @ Lexington Park, MD. In 1992 BRAC pushed the NADC Navigation Department (Code 40) to transfer the NCCOSC (Naval Command, Control and Ocean Surveillance Center) Research, Test and Evaluation (RDT&E) Division to San Diego, CA. NCCOSC works with Space and Naval Warfare Systems Command (SPAWAR). SPAWAR supports over 150 programs managed by the Program Executive Office (PEO).
  7. Nicely done and you cant beat the community effort. Hand salute!
  8. I now pronounce you man and Cobra. Also here are two shots of Whiskey for you on the house! Both 1990 Van Nuys Air National Guard base before everything moved to NAS Point Mugu
  9. I'm setting the Way Back (WABAC) Machine for December 1986 to check out the Marine Corps AH-1W Super Cobra. Sherman and Peabody were in the Army National Guard so all they had were APH-1 and APH-5A helmets. They are also not wearing their Nomex but beg you to show mercy on them and not give them a bad OER or NCOER. As stated they are Army National Guard which means they routinely fly naked. Sorry about that! This article first appeared in 'Combat War & Weapons' published by Modern Day Periodical, Inc. in December 1986. Click for a 150 dpi version that will open in another tab at a more readable version. I like what Col. M.F. Pixton III had to say about the Apache on Page 4. I can only image what the 'M.F.' stood for in Col Pixton's name. =) Also, sorry for the wrinkly last few pages which were the result of a damp basement. I promise I was not gesticulating to helicopter pictures again although my wife has actually said these words to me, "I'm dead serious. It's the Huey or me! Take your pick!" =)
  10. Good details Bryan in all your posts which I appreciate. Also immensely appreciate your insights and images which are rare as hens teeth from someone on these programs and who has the goods on the saucy bits. I realize I just have a different outlook on certain points based on my own experiences. Not intentionally leaving out dates for any purpose just the official dead date matters because it means no future funding. Dead is dead. Pack it up and Bye bye team which sucks from experience. I actually forget more than I remember, TBI & mini-stroke, if it's not written down. . "In 1972 we did not need a 200 Kt attack helicopter that would spend most of its time hovering in the trees." One of the major outcomes of Lam Son 719, Feb 8, 1971 – Mar 25, 1971, was the AH-1Gs ability to get in fast and low and the Cobra as a result fared better than the Charlie model gunships which suffered more losses. The Snake pilots modified their standard roll in from high altitude to defeat the radar tracked AA guns by coming in low and FAST so it was speed that saved them. Your point makes sense only if the doctrine developed is the game of cat and mouse; pinpoint targets with the Scout using MMS (my avatar), have the attack helicopter unmask and fire AT against those targets, then go back to hiding but little sense in other scenarios where speed is a factor in survivability. I wouldn't hedge my bets on Hover and Hide doctrine which has its roots in the Cold War Soviet Fulda Gap scenarios. Speaking of speed, Lockeed/Sikorsky's newest offering in the latest Army Aviation program, FARA (Future Attack Reconnaissance Aircraft), S-97 Raider has reached a top speed of 220 knots. Either Lockheed didn't learn anything from Cheyenne or there is a reason for the 'Need for Speed'. Lockheed/Sikorsky are the likely candidate for the awarding even if they once again lost a prototype only this time in a hard landing and with the coaxial rotor system are trying to solve vibration issues, again. Like Stalker6 said Im sure the Cheyenne program would've worked had the development team been given the chance to do so but they were dead before they were officially dead and Apache was the latest wet dream. Just like OH-58F kept going and what we did sits on a pole now at AMRDEC on Redstone instead of bagging flight hours Cheyenne was also only going through the motions. Good points, and POV.
  11. The flex sight could be elevated and adjusted in many ways. You could move it laterally left and right and vertically up and down. I have Bravo-6 pilots for mine and am modifying their M-60 tank crew for door gunners. Much more dynamic IMO. And yes Academy/MRC shorted us all 1 door gunner in their kit and as you pointed out have short comings. The answer on the crew is 4. You had two have to gunners to cover on each side and the break coming out of a gun run and 2 pilots in the event one was incapacitated. Your typical flight crew consisted of the AC, Aircraft Commander and senior pilot, the Peter Pilot which is what the Co-pilot was called who had lower hours than the senior and was still proving himself to rate an AC slot, your CE Crew Chief/Door Gunner who was in charge of the maintenance and another Door Gunner who was cutting their teeth for their own CE slot once they also proved themselves worthy. Here are some images of the reflex sight from USAAM (US Army Aviation Museum) courtesy of Ray. You can see it in different positions throughout these images.
  12. The Cheyenne was killed 9 August 1972 not in 1969. 10 November 1972 is when Kenneth Rush, Deputy Secretary of Defense approved the release for RFP to industry. It was 29 March 1973 when Gen. Creighton W. Abrams, Chief of Staff, US Army made his 'Big 5' announcement a decade after Secretary of the Army Cryus B. Vance did on AAFS which lead to the Cheyenne: "The weapon systems which I will now discuss are referred to as the 'Big Five'. They represent a family of weapons essential to our success on the battlefield of the 1980's...The "Big Five" are the most important of today's weapons developments for tomorrow's Army." Gen. Abrams to 93rd Congress, subcommittee on Defense, US Senate, first session 29 MAR 1973 1. An Advanced Attack Helicopter (AAH) AH-56A replaced by the YAH-64A 2. New main battle tank (XM1), M1 Abrams 3. A mechanized infantry combat vehicle (MICV), Bradley IFV 4. A modern utility and transport helicopter (UTTAS), Sikorsky Blackhawk 5.

Callaway, reveled that Bell Helicopter and Hughes Helicopter were winner of a competitive evaluation designed to provide the US Army with an AAH in early 1980 9 AUG 1972 Secretary of the Army officially terminates the Lockheed AH-56A program and simultaneously announces initiation of a program to develop an advanced attack helicopter 10 NOV 1972 Kenneth Rush, Deputy Secretary of Defense approved the release for RFP to industry JUN 1973 Contract award.

It was JUN 1972 when Callaway awarded Bell and Hughes competitive awards for what would become the Apache. Three months later AUG 1972 he killed the Cheyenne. The AH-1G was already in the pipeline around the time the first UH-1C models made it to Vietnam and the subsequent Mike models arrived in-country or the Charlies already there got the Mike model engine upgrade. The powers that be only kept the AH-1 alive with upgrades until they could move their approved AAH program to PROD and in this case it heralded a move away from Bell Helicopter. I was there for the death of the AH-1, UH-1, RAH-66, and finally OH-58. 3 out of 4 of those were Bell Helicopter. I left PEO AVN at the CH-47J.
  13. What the Cobra offered, and the Marine Corps so brilliantly still understand, was an ease of use supply chain were similar components are on hand versus the hodge podge Army Aviation became of disparate parts in their inventory system. The Cobra also met the requirements for what was then called AAH, Advanced Attack Helicopter. AAH was superseded by AAFSS, Advanced Aerial Fire Support System, which was the AH-56A Cheyenne they then killed for the Apache Mafia crowd and to please the Air Force who sashayed all the way to Washington to complain because the Cheyenne had 'wings' and was taking over a role the Air Force insisted they solely owned, CAS, Close Air Support. A cat fight that would see the death of fixed wing Army Aviation assets leaving only rotary wing in Army Aviation and a mandate that any stub wing not have ailerons and be fixed to a short length. Col Jay D. Vanderpool stated one of the reasons for selecting the Cobra for the AAH program was: "The Bell Huey Cobra, although a Tandem cockpit gunship, employed proven aerodynamic and structural components which were already in the Army inventory. Additionally, the Huey Cobra employed the Lycoming T53-L-13 engine which was an outgrowth of the Lycoming family of engines long tested in the UH-1 family of utility helicopters. Over ninety percent of the required repair parts were common items in the Army maintenance inventory. Existing tools and test equipment were compatible with the Huey Cobra." I guess because Im a sucker it's a world I largely miss until I get the reminders of the personality disorders you often encounter and the need to come to work in a raincoat to protect yourself from the constant streams from pissing contests. Then there are the lessons learned that often occurs in fielding anything signed off on and then put into operation. Are you in good hands?
  14. I already had a profile for Miss Mini that I did.
