#avgeek #aviation #RoyalNavy #aviationlovers – The remarkable Westland Wyvern naval strike airplane featured contra-rotating propellers and a mighty, behind-the-cockpit 3,200-hp Rolls Royce Eagle engine. This configuration allowed a cut down nose... 1/ ImageImageImageImage
2/ optimized for aircraft carrier naval aviation. 127 built, 1946–1951. Six W.34 prototypes↖️. 7 x TF.1 pre-production planes↗️ built in 1946. 9 x TF.2 ↙️↘️built in 1949. These used either a Rolls-Royce Clyde or 3,560 hp Armstrong Siddeley Python turbo-prop. ImageImageImageImage
3/ There was a single Westland Wyvern TF.3 two-seat trainer converted in 1950 from one of the previous aircraft. By the way, Wyvern was a legendary dragon. The definitive model was the TF.4, which was later renamed S.4. So what are TF and S (torpedo fighter? Strike?)? Image
3/ 98 x TF.4 ↖️↗️↙️built 1948-1951. Total all versions: 120; Fleet Air Arm service: 1954 to 1958. 68 accidents; 39 lost from flameout on catapult launch, combat, etc.; 13 fatalities. 4 × 20mm; 16 × RP-3 underwing rockets; 1 torpedo! Compare to smaller engined TF.1↘️. ImageImageImageImage
5/ I wish I'd found the TF.1 profile earlier to better explain the fuselage's evolution. Apologies for naming the above post "3/" a second time. Please note any errors, comments, etc. TY @clark_aviation for teaching me about this plane. Source: en.wikipedia.org/wiki/Westland_… Image
@clark_aviation 6/ It's fairly common for me to make a "gee, I wish I had a #TwitterEdit" typo, etc., in my threads, but I didn't even notice this huge one about the engine placement. Thank you @JmeDubya!
@clark_aviation @JmeDubya 7/ Okay, I think I finally have it. :) The prototypes had the mid-engine and thus smaller nose. So did the TF.1 as in this↖️ great photo from 1000aircraftphotos.com/Contributions/…. The TF.2↗️, TF.3↙️and TF.4↘️ all had the front-engine configuration. Is this correct? ImageImageImageImage
8/ If you enjoyed this thread, you might enjoy this short P-63 thread (28-photos including cockpit details)... The P-63 featured a mighty, behind-the-cockpit engine like the Westland Wyvern did to start with...
9/ So nope, not even my Westland Wyvern post 7/, above, was correct. I'm grateful to Jamie @JmeDubya for more on the matter. :)

#PoliceReform #TyreNichols #Tyre #Video #Riots - Bodycam footage pf Tyre Nichols' murder by 5 police officers is due for release tonight. Police across USA are bracing for riots and violence. But violence will only harm and destroy communities with NO benefit. Please don't do it.
#RodneyKing #TyreNichols + Memphis, HELL NO trend. 1992's Los Angeles Rodney King riots did great harm. This was both the immediate damage and massive subsequent economic devastation as companies and customers stayed away. What do #riots do to the communities they devastate?
3/ #PoliceBrutality #TyreNichols: People have every right to be angry. I'm angry. 😠😠😠But for once, the system actually seems to be working. The five #Memphis #police officers have been fired and arrested. Quickly.

1992 Rodney King Riots #StopTheViolence:

#FirepowerFriday #WW2 #ships: #Germany's mighty and handsome 52,600-ton 8x15" battleship Tirpitz at speed↖️ and Tromso fjord, #Norway↗️. ↙️↘️Perhaps on November 12, 1944 when she was sunk by RAF Lancasters. Her clean lines betray a lack of AA. Photo: ACME.
2/ Per reddit.com/r/WarshipPorn/…, here's a #USNavy manual excerpt on Tirpitz identifying what is what.
3/ Tirpitz was, of course, the second and last ship of the Bismarck-class battleships. These diagrams from forum.worldofwarships.com/topic/199855-t…, etc., show her gentle evolution over time, especially ↖️↗️↙️where we see improvements in AA, radars and camo. ↘️ is similar to ↗️.

T-34 #military #history – The apex of Soviet Christie suspension #tanks is the 33 mph T-34/85 with the L/55 D-5T 85mm main gun. Note: the larger vehicles (T-34/76, T-34/85, British A-27 and A-34) had five wheels a side).
#military #history – The most-famous Christie suspension vehicle is the Soviet T-34/76. It lacked the hybrid solid rubber tire road wheel/track configuration but just superb wide traction tracks helping it sprint over terrain its opponents couldn’t handle.
3/ #TankTuesday I'll post four T-34 interior shots in a moment as a reply to this later model T-34/85 with the larger gun, larger turret, and five-man crew instead of the original T-34/76’s four-man crew.

#RussiaUkraineWar #Challenger2 #UkraineArmy Challenger 2 tank: 447 built 1998-2002. World's best tank? L/55 120mm barrel. Crew: 4. Armor: 2nd gen. Chobham. 63 long tons! 1,200 bhp; V12 diesel; 37 mph. Ukraine to get 14. Great video from @PhilLoder. 1/
@PhilLoder 2/ Challenger 2 has digital fire control computer, laser rangefinder, 8 periscopes and 2 x 7.62mm machine guns. How would it fare vs. #RussianArmy's T-72B3, T-90 / T-90M or T-14 Armata? @Burntime0101's great photos show Megatron emitting a smoke screen!
@PhilLoder @Burntime0101 3/ Challenger 2 is based on the similar looking Challenger 1 but shares only 3% of the parts! At the gun’s root is the big boxy Thermal Observation and Gunnery Sight II (TOGS II) for night vision. It relays to the gunner's and commander's monitors and sights. ImageImageImageImage

#USNavy #USAF #avgeeks #aviationlovers - NATF-22? Yes, there could have been a navalized F-22 stealth a la F-14 Tomcat with swing wings, Mach 2.25 supercruise, heavier landing gear, and so much more. So why did the US Navy opt for the F-18 and F-35 instead? I'll tell you... 1/ Image
2/ Congress wanted the NATF-22 but the US Navy pushed back. The swing wings would have compromised stealth and added to the maintenance woes. As it was, the F-14 was already far too expensive especially in the absence of the #USSR's military, which is why the F-14 was retired. Image
3/ The naval F-22, aka Sea Raptor, would have been slower than the F-14 and cost more. The F-22's unit cost was, ballpark, $138 million. A navalized one surely would have cost at least 20% more based on F-14 vs F-15 costs. en.wikipedia.org/wiki/Lockheed_… Image

#Hurricane #USNavy #OTD: December 18, 1944, Admiral Halsey catastrophically orders the US Navy’s vaunted TF38 into #TyphoonCobra. TF38 has seven fleet carriers, eight battleships, ~60 light carriers, cruisers, and destroyers. In all, USA loses three... 1/
2/ destroyers on Dec. 18 killing 790 sailors. USS Iowa @ussiowa, CL Miami, etc., damaged. Light carriers Langley and Cowpens (above tweet) roll through 70 degrees, sending airplanes overboard or into each other, starting big fires. 146 aircraft lost!!!
3/ In contrast, USA lost 123 aircraft in June 1944 Battle of the Philippine Sea. Destroyers Hull↖️, Monaghan ↗️ and Spence ↙️ sink. Maddox ↘️ and others are pounded but survive. 30 US Navy warships sunk or damaged total! #disasters #WW2 #Pacific #Weather
