June 30th, 1949: Observers from several nations were present for the first Royal Thai Navy Sinking Exercise. As the day before the official exercise kicks off, it consisted of ceremonial duties, as well as some Navy Personnel assisting local fishermen in removing their pots and nets from the exercise area and getting the catch in. The old Cruiser Sexupa, which had been slated for future scrapping, was ceremonially decommissioned, and towed to the target area. Additionally, one Perla Class Submar...
I'm looking at some air warfare ships for Thailand, as opposed to the current crop of general purpose cruisers and ASW oriented DDs. I'm also looking at using Diesel propulsion on some ships. Are there any particular restrictions that I need to know about?
Thailand would have been interested if we weren't already building a full class of almost identical ships that have our own guns, engines, and other logistics.
It was very obviously set up as a salute, and fired directly out to sea sea which would be towards his own ships. Also, a salute is typically a low power charge, so a trained eye would definitely know it's not a war shot. But as to the whole thing, we are talking about a navy which hasn't done a port visit at all in 10 years, much less a friendly port visit with a full task force. I would figure that there'd be some lookie-loos following the TF out of the harbor, and once out to sea where he sho...
June 18th, 1949: Exactly one week after mooring at anchorages in Manila Bay, the Royal Thai Navy Task Force 1-1 weighed anchor and put to sea to complete the longest distance cruise made by a RTN fleet in a decade. Admiral Kosol watched from the flag bridge of TNS Taksin, now officially worked up enough to handle the duties of flagship for the remainder of the training cruise. Admiral Kosol knew that the next leg of the voyage would be the hardest, with his ships taking the week respite to make ...
I've seen it sourced multiple times on NavWeaps when you look at the 14in US guns mounted on the Standard class BBs. Looks like the delay coils only delayed .060 seconds on the center gun of the Triple Mounts. I did see it noted that the 3 gun mounts of the later BBs did not have that severe of an interference problem due to the guns being spaced wider on their separate sleeves.
The us standards had terrible issues with triples having insane dispersion. They put delay coils in the firing circuit for the center guns of each turret in order to alleviate the problem. We are talking about a quarter second, but enough to allow the blast from the outer fund to dissipate sufficiently.
June 13th, 1949: Royal Thai Army troops officially opened the new Jungle Warfare Training Center, which is sited on approximately 50 square miles of land in northern Thailand that contains a mix of open, jungle, and hill terrain. This training center is large enough to allow for battalion level exercises in realistic settings. The Royal Thai Army, now divided into Brigades rather than the venerable divisions, demonstrated its ability to move troops rapidly through multiple terrain types using a ...
June 12th, 1949: Krabl Aeronautics announced today that a full scale model of the XB-1 bomber prototype has been sent to the United States for full-scale wind-tunnel testing at NACA. The press release states that it was due to a need to rapidly address any lingering issues with the larger aircraft and that NACA had the most immediate availability of its facilities. Questions about more regional wind-tunnel testing and research facilities were not answered, but it's likely that regional tensions ...
June 11th, 1949: Admiral Luang Yuthasastr Kosol lead Task Force 1-1 of His Royal Thai Majesty's Navy into Manila Bay today for crew rest and a visit of friendship and goodwill between neighboring maritime nations. HRMTNS Taksin leads the procession into Manila Bay, and moors pierside with the Admiral onboard, the other ships in the task force taking anchorages to respect the Filipinos' pier space for their own commerce. Admiral Luang Yuthasastr Kosol invites local dignitaries and ambassadors fro...
Think flying wing with a rudder. The rudder can significantly assist with lateral stability as well as it provides an anchor to sideslip problems endemic to flying wings. And yes, there's smaller scale wind-tunnel testing, though as you noted Thailand would have to outsource prototypes to large nations that have the proper full-scale wind tunnels if they wanted to do full testing. Also, the chief engineer of Krabl Aeronautics was formerly from Lockheed, so he has more than a passing familiarity ...
June 7th, 1949: Krabl Aeronautics announced the crash of its XB-1 testbed glider. Chief Engineer and President James Yenbamroong advised that further modifications to the first fully indigenous Thai combat aircraft design would be made and that he was confident in the basic design of the plane. Much secrecy has surrounded the activity of Krabl Aeronautics, especially since a shipment of Rolls Royce engines was noted to have been delivered to the nationally backed aircraft company. This has been ...
Ahh wonderful. Thanks Hood for clearing that up. Krabl is also working on a bomber aircraft prototype using the same powerplant arrangement and general airframe concept, just scaled up to 12000kg, which would put it in the same weight class as the DH Mosquito, roughly. Any larger than 12000kg and it'd need to go up in engine size or number to compensate since ~12000kg with 2 engines gives a .3 T-W. Past that, you'd need to double the engines (or go with bigger ones, that's not an option for Thai...
It's possible that it's not. And I'll have to confirm with Hood that it is the Derwent V that is being sold to Thailand. So the figures could drop a bit, but not out of the realm of being at least reasonably competitive with regional rivals. Based on the Derwent V being historically a 1945 engine, and the Derwent 8 being the quintessential engine for the Meteor before the Brits upgraded to better things, I would presume that the Derwent V is indeed in production. If it does wind up being the Der...
I took some historical figures and did some rather simple changes to them. However, I agree with you on most of this, so I'll get back to work on the basic design specs to put it more in line with what's possible. Actually just looked up some engine weights, which was quite interesting. Also caused me to revise my weight projections significantly as the historical engines were not only less powerful but also 150kg heavier than the Derwent V. Also, keep in mind that there are 2 of those engines, ...

May 30th, 1949: Alert observers in Krabl noticed two strange looking gliders being towed by a RTAF Ju-52 today. While questions were asked, no information is forthcoming from Krabl Aviation about the nature of these gliders or what they might be testbeds for.
May 7th, 1949. The Thai National Aircraft Company announces a partnership with De Havilland Limited in developing and producing new aircraft to be built in and for the Thai and Southeast Asian market. Officials from both companies were present for the announcement, which detailed that TNAC and De Havilland were both working on military and civilian projects, with De Havilland providing engines and engineering expertise and TNAC providing major design and manufacturing services.
