0319 BMP - 4 classes and 5 BigB shipsides: Elco 77ft PT (US) - 46 ships, 21 on the map on 12/7/41. 1 Shipside. One upgrade (1/44) Vosper 72' MTB (Indian) - 24 ships, all arrive on 10/10/43 or later. 2 Shipsides. One upgrade (4/44) BPB 60' MTB (Brit) - 8 ships, all 8 on the map on 12/7/41 (Hong Kong). 1 Shipside. No upgrades TM-4 (Dutch) - 12 ships, all 12 on the map on 12/7/41 (Java). 1 Shipside. No upgrades Normally we'd go with "majority rules" and use the single Elco shipside for all, and that would be it. However, it would be nice to see more of them in game, and there is a rationale for doing that: 12/7/41 - Start with the BPB 60' MTB: All 8 of these appear on map in Hong Kong at game start. Historically they didn't last long and they'll be in combat right from the get-go so we'll use this shipside for the month of December only. With regard to colors, armament and profile, the BigB shipside captures them perfectly (see Item #1) so no changes are necessary. 1/1/42 - Shift to the TM-4: The 12 Dutch PTs also had a short existence (the database shows that all were sunk by 3/2/42) so we'll use their graphic for three months. Once again the new shipside does a good job of capturing the profile of this class, and has nice camo to boot. I could only find a single low-res photo (#2) to use for comparison purposes, but it confirms the profile and nicely captures a torpedo out of the tube and on its way into the sea. 4/1/42 - Insert a modified Elco 77ft PT: BigB's new shipside is sort of a forest green, which is one of many official color schemes, but in the early war these were a different color. Here's a description of the colors used by PT Squadron 3: "They were originally painted overall Navy Gray (No. 5) with Outside Dark Gray (No. 5-D) decks. Once the boats reached the Philippines, they were repainted in Measure 1, which was overall Overall Dark Gray (No. 5-D). At some point, probably in April 1942, the Ron 3 boats were painted in some shade of green." Going through the ship modeler forum, most people use a green that's more of a dark, dull olive (#3), so that's what we'll use here. Otherwise, the armament and profile matches the look of early war PTs (#4). 12/1/42 - Shift to a modified Elco 77ft PT: The Elco has an upgrade at this time which adds radar and a large rear mounted 20mm AA gun (#5). Both will be added to the shipside, and we'll lighten the green just a bit. The line drawing also shows a large front mounted gun, but it is absent from the database so we'll ignore it (plus, as discussed earlier, weapons could vary significantly from one PT to another anyway). 10/1/43 - Shift to the first (non-camo) Vosper 72 MTB: This is when the first Vospers arrive, and there's also a strong likelihood that many of the US Elcos will have been sunk by now, so the numerical advantage is probably more or less equal between the two types. Also, the three US PT classes look very similar, so this allows one of 3 bmp groups to maintain a different profile and color. As for this shipside, the armament, colors and profile are correct (#6). Although the database specifies a front mounted 20mm Oerlikon, that appears to be a feature of the North Atlantic MTBs, not those which were built for the Indian Navy (to whom all 24 in AE belong), so we won't alter the shipside. As for their usage, hyperwar has this to say: "In June 1943 three flotillas of Vosper 72 ft. Motor Torpedo Boats were commissioned in Bombay and Calcutta. Later 22 boats of these flotillas formed into the 16th and 17th M.T.B. Flotillas based at Madras and Vizagapatam. Both flotillas were manned entirely by Royal Navy ratings with R.N. and R.I.N. officers. Owing to their limited operational range and absence of targets for their torpedoes, it was decided by the Admiralty that M.T.Bs were of no practical value in the South-East Asia Command and therefore in July 1944 both flotillas were paid off and placed in care and maintenance." 4/1/44 - Shift to the camo Vosper 72 MTB: The Vospers get an upgrade in April 1944, so the new shipside will reflect that. Other than camo, there's no visible change in the armament. Here are the new shipsides, in sequence of appearance (Items 7-12): [image]local://upfiles/25668/57CA7D567D0547FD84655EB6EA2204A1.jpg[/image]
