Outside in the heat again, an M40 Walker Bulldog.

View attachment 813454

It may be an original Thai M41, or it may be a M41GTI: M41 modernized by German company GLS for the Royal Thai Army. Fitted with a new MTU MB 833 Aa501 diesel engine developing 442 hp (330 kW), enabling the tank to reach speeds of up to 60 km/h (35 mph) and increasing its range to 600 km (370 mi). The 76 mm gun was also coupled to the MOLF 41 digital fire control system with thermal imaging sights and a laser rangefinder, as well as a new co-axial Heckler & Koch HK21 machine gun.
 

Thanks for that Green Knight, you're probably on the money in it being an M41GTI. My knowledge of tanks isn't that great, particularly sub types.
 
Thanks for following along, guys. Continuing on with this, as previously mentioned, in the late 1930s the Siamese Air Force bought its first monoplanes, which comprised 6 Martin B-10s in 1937, followed by 12 Curtiss Hawk 75Ns in either 1937, 1938, or 1939, which I am not certain about because I cannot find an accurate date, let alone a year that the Hawk 75Ns were ordered and arrived in Thailand. One source on the P-36 states that the first foreign order for the P-36/Hawk 75 was from China, which ordered the Hawk 75H in 1937, a simplified Hawk 75 designed for export with fixed undercarriage. Next up was Argentina, which ordered the Hawk 75O, again, the fixed gear export variant in mid 1938, as well as the Martin B-10 (Martin 139), like Siam, so did the Siamese order their Hawk 75Ns around the same time or was it a year earlier or later? The source I am using on Thai aviation states that Siamese Hawk 75s were ordered "shortly after" its order for Hawk IIIs, which took place in 1935, far too early given the first export examples went to China in 1937, so does that mean Siam received its the same year? If anyone can come up with a conclusive answer and link to their source of when Siam received its Hawk 75Ns, I'd be grateful.

The sole surviving Siamese Hawk 75N is a beauty to behold, but there are a few issues with it, apparently. It's colour scheme is inaccurate in terms of the shades used and its Madsen MG pods are too bulky, the pods should be shallower and squarer in profile, nevertheless it was neat to see it in the flesh.

Receiving a total of 25 - again, sources differ, the Hawk 75N was Thailand's first modern fighter and with the declaration of war against France in October 1940, the Hawks went into action against French forces based in French Indochina. The war was brief as in January 1941 the Japanese, who had their own interests in the region provided mediation between the two sides and an Armistice was signed on the 28th. As previously mentioned, early in the morning on 8 December 1941 local time, Japanese troops poured into Thailand. There was token resistance, but Marshall P ordered the Thai armed forces to stand down and later that same day signed an armistice with the Japanese. The reason why Japan invaded its erstwhile ally was that its military required passage across Thailand to reach Burma, and to transit down the Malay Peninsula toward Singapore. By this time, the RTAF had nine Hawk 75s based at Prachuap Khiri Khan Airfield on the Kra Isthmus where Japanese forces landed and three of them were destroyed outright during the attack on the airfield. On 21 December a Friendship Pact was signed between the two countries, by which time Thailand had declared war on the United States, its largest supplier of combat aircraft by that time. This was the culmination of deteriorating relations between the two countries, as Thailand's decision to order Japanese bombers and attack aircraft in 1940 angered the US, resulting in arms already on route to Thailand to be seized. This included an order for North American NA-68 fighters and NA-69 attack aircraft, which were impounded in Hawaii. This meant Thailand was desperately short of modern fighters given the small number of Hawk 75Ns, leaving the RTAF to have to rely on its fleet of Hawk III and Corsair biplanes as its most numerous fighters heading into WW2. Given the friendship pact, the Japanese allowed Thailand to function independently of Japanese rule despite the presence of the Japanese military in country, enabling its military independence and further bolstering of the RTAF with Japanese aircraft.

Anyhoo, the gallery from upstairs. From left to right, de Havilland Tiger Moth, Tachikawa Ki-55, Breguet XIV replica, Nihon Kogata Tobi and Nihon Kogata Hato gliders, Piper L-4J, Stinson L-5B.

_ADP9329

This is a remarkably rare survivor, it is a Nihon Kogata K-14 Tobi guraida, which was one of three gliders given to Thailand by the Japanese army in 1941 around the same time as the RTAF received its Nakajima Ki-21s and Ki-30s, to aid in flying training. These were the K-14 Tobi, a Nihon Kogata Ku-15 Hato, and a Nihon Kogata Otori. It's incredible that the former two survived the war. Based on the Grunau 9 primary training glider from Germany, the Tobi was one of several gliders manufactured in Japan based on the Grunau 9, including aircraft by Itoh Aircraft Company, Mizuno, Kyushu Imperial University, and the Ministry of Education.

_ADP9406

The Nihon Kogata Ku-15 Hato guraida was an improvement over the Tobi and had essentially the same basis in the Grunau 9, but was fitted with a streamlined enclosed cabin for the pilot and a more refined wing design. Again, this is a rare survivor, possibly the only one of its kind left in the world.

_ADP9407

From inside, we go outside into the heat of the darkening evening and practise our low light photography. I'm quite pleased how well these photos came out. With a bit of tweaking they are better than I thought they would be. 43 Sqn F-68F.

_ADP9403

211 Sqn A-37B with the 211 Sqn Bird of Prey nose art.

_ADP9404

Indigenous RTAF-4 Chanthra. Based on the DHC-1 Chipmunk, 12 of these primary trainers were built by the RTAF's Science and Weapon System Development Centre, the first one completed in 1972. This one is the fourth example built and was completed in 1974.

_ADP9410

This single example of a Pazmany PL-2 was bought by the RTAF in 1974 to investigate a new primary training aircraft, but the design lost out to the CT/4A Airtrainer previously described.

_ADP9412

Another indigenous aircraft developed by the RTAF Science and Weapon System Development Centre, this is the RTAF-2 and it was based on the Fuji LM-1 Nikko, which in turn was based on the Beech Bonanza, which is obvious when looking at it. Only the one example was built, in 1957 as a liaison aircraft.

_ADP9413

461 Sqn GAF N-22B Missionmaster, or Gonad in Aussie vernacular! The Missionmaster was an Australian STOL aircraft, essentially the military variant of the Nomad, of which the RTAF operated 22.

Great pics and info Grant!

Lot of unkonwn planes to me.
 
A wee update on the receipt of the Thai Curtis Hawk 75s. I found in Green & Swanborough's big book The Complete Book of Fighters that it states that Argentina received 29 Hawk 75Os in November 1938 and continues with the following: "Delivered simultaneously to Thailand were 12 Hawk 75Ns...", which is the best lead I've had so far, pointing to an end-of-1938 as the delivery date. Then I found this in Bowers' Curtiss Aircraft 1907-1947 (Putnam, 1987 reprint) states "delivered to Siam (now Thailand) starting in November 1938. C/ns 12756/12767" Looks good to me...

A couple of minor corrections to my thread, this is an F-5B rather than an F-5F Tiger II as I originally wrote, despite the "Tiger" written on the nose.

_ADP9241

This V-93S was built in Siam, which makes it possibly the oldest surviving Siamese built aircraft.

_ADP9254

Corrections made in the text. More to come soon...
 
Back into it. Some rotorcraft inside the museum. The RTAF operated a total of four HH-34B Huskies as search and rescue aircraft and it was the service's first dedicated SAR helicopter.

_ADP9433

The RTAF's first helicopter, four second hand examples of the the Westland Dragonfly were ordered from Britain, although only three reached Thailand, the other crashing before delivery. Although liked in the RTAF, the humid climate sapped the Dragonfly's performance. I saw a bunch of kids jumping in and out of the aircraft in this hangar, including the Dragonfly and initially I thought about telling them to get out, - my artifact preservation instinct kicking in there, but I hesitated because I didn't want to get into trouble for harassing someone's kids in a foreign country.

_ADP9434

A different take on the same airframe, a Sikorsky R-5 tail dragger, the only one operated by the RTAF, demonstrated poor performance owing to the climate and no further examples were ordered.

_ADP9436

Only four UH-12s were operated by the RTAF, preceded by a single Hiller 360 being delivered in 1950, three years before the UH-12s.

_ADP9437

The unusual Kaman Huskie looks like some convoluted insect and is a visually intriguing aircraft from every angle.

_ADP9438

More than 60 CH- and UH-34 airframes were operated by the RTAF, some of them coming second hand from Laos. A further 19 turbine powered S-58Ts were also bought. Two of the RTAF's UH-34s were leased to Air America during the Vietnam War.

_ADP9442

Nine of these Kawasaki KH-4s were designated UH-13 in RTAF service.

_ADP9445

Classic UH-1H Huey, of which a total of 38 were operated by the RTAF, the first of which arrived in 1968, with more being progressively ordered over the next decade. Some of these examples were former Laotian and South Vietnamese examples.

_ADP9447

One of two Bell 212s ordered specifically for the King's Flight in 1976, although they were not in service as royal transports for long, as an order for Bell 412s saw them passed onto 201 Sqn as VIP aircraft. I'm not sure what all the wee boxes represent in this display.

_ADP9449

Back into the air conditioned comfort of the main building, the Boeing 100E from a higher plane. Note the festively lit up exterior.

_ADP9463

Inside one of the halls was an art gallery, the pictures within which I really liked the look of. They are all by an artist whose signature is simply Wanchai. Here are some of my favourites. I'll caption them to the best of what I can find.

A Curtiss Hawk II in combat with a Vichy French biplane with action in the skies beyond. This is likely in the early skirmishes between Vichy forces based in Laos and Cambodia during air raids against Thailand late 1940, in particular bombing raids in the Nakhon Phanom region in the east of the country.

_ADP9520

A watercolour of a Nieuport Delage NiD.29, of which the RSAF operated 52 examples, 12 of which came from France in 1923, but the rest being manufactured locally. This was the RSAF's principal fighter until the arrival of the Hawk IIs in 1934, by which time it was decidedly outdated.

_ADP9521

One of four Nieuport 11s operated in Siam, which were bought from France in 1918 as the country's first combat aircraft.

_ADP9522

A Breguet XIV, a type that served the Siamese well, remaining in service from 1919 until replaced by Vought Corsairs in 1934. A total of 42 Breguet XIVs were operated by the RSAF as bombers and reconnaissance platforms, of which 29 were built under licence, beginning in 1924, a remarkable effort for an Asian nation in the 1920s. A single example was bought especially to serve as an ambulance.

_ADP9524

Another significant type in RSAF service, a Vought V-93S Corsair, of which 12 were initially bought in 1934, with a further 75 built under licence. This type became ubiquitous, serving initially as a two-seat fighter, but also as a land-based and ship-based reconnaissance bomber. We'll visit one of the very ships the V-93s served on soon.

_ADP9529

A Ki-27b Ota in action against an AVG Flying Tigers P-51D wearing a sharkmouth, while a P-38 streaks by in the background. This painting depicts a combat by Flying Tigers P-51s and P-38s and P-51s of the 51st Fighter Group conducting sorties near Chiang Mai on 11 November 1944. The combat is recorded here in detail, saving me from repeating it: Royal Thai Air Force Nates ~ Ki-27 Aces Extra 1

I like that one of the P-38 pilots said that the Ki-27s were "manoeuvrable as hell, but slow as hell..."

_ADP9531

A Mitsubishi Ki-30, of which 25 (one source says 20) were bought from the Imperial Japanese Army Air Force, in action. These remained in service until 1951 and saw action against Vichy French forces in French Indochina in late 1940, early 1941. This action is likely an attack on French positions in Siem Reap, Cambodia on 10 January 1941.

_ADP9526

Another view of the action between Thai Ki-27s and US P-51s and P-38s on 11 November 1944 referenced above. In total, the RTAF operated 12 Ki-27s received second hand from IJAAF stocks in Manchuria, of which three were shot down on 11 November 1944. Replacing the RTAF's Hawk 75Ns, the Otas were supplemented and eventually replaced by Ki-43s received in 1943, with only one serviceable Ota remaining by November 1945.

_ADP9533

One of 27 (one source says 25) Ki-43 IIbs, the Thais referring to them by their Japanese name Hayabusa, that served with the RTAF, this one is seen attacking a B-29 Superfortress. This was something that happened on a regular basis, as Bangkok was attacked by B-29s on a few occasions, notably actions on 5 June and 2 November 1944, when the marshalling yards at Bang Sue were bombed by 55 B-29s. Thai and Japanese Hayabusas intercepted the bombers and one was damaged by Flt Lt Therdsak Warrasap, but he was shot down by the B-29's return fire. It is possible that this is what is being depicted in this painting. The Ki-43 was the RTAF's primary fighter until 1949 (one source says 1948). By the end of the war however, only a handful were serviceable and parts were scavenged between aircraft to keep them in the air.

_ADP9534

Finally for today, an F8F Bearcat. As previously mentioned, the F8F was the final and most numerous piston engined fighter in RTAF service, with 204 being operated in total. Although the first 40 of these were delivered from the USA aboard the escort carrier USS Cape Esperance in late 1951, 38 examples came third hand from the Armee de l'Air. In RTAF service the F8F was used as a fighter and ground attack aircraft, seen here loaded with weapons on its underwing pylons.

_ADP9536

Stay tuned for more fabulous artwork and the last of the night shoot aircraft at the RTAF Museum.
