Interesting. A little history of one of the last of its kind, and literally that last one remaining... our British cousins taking their hack at it..

While we discuss big metal things , this is a reminder of how massive the oceans are:
she most likely sank.of course.
well known we know less about whats under water up to miles deep (70% of this rock is under water), on this planet than stuff off of it.
Atlantic averages 13,000 ft deep (almost 3 miles), some parts flat, others like the Grand Canyon. With no good starting point, and good surface search, she's gone forever.

USS Oklahoma met a similar fate. When Pearl Harbor was attacked, she was berthed next to USS Maryland. Because of that, Maryland was spared serious damage, but Oklahoma was torpedoed and bombed and the torpedo damage caused her to capsize. Salvage operations began in mid 1942 and lasted almost a year. After she was righted it was determined that she would not be repaired and returned to the battle line partly because of the extent of the damage but also because she still had the reciprocating engines she was originally built with (her sister Nevada was built with turbines). She remained at Pearl until May of 1947 when she was set to be towed to San Francisco to be scrapped. Around 500 miles from Hawaii, while being towed by two ocean going tugs, the trio were hit by a storm and Oklahoma began taking on water. The tug captains saw that she was listing, contacted Pearl and were told to return. However the list was increasing rapidly and the tug captains had to loose the cables or risk being dragged down with her. Oklahoma sank almost straight down. Her exact location is unknown.

One of our own folks ... older thread, never got into this one. Still relevant.
Cat 988 refresh.
Okay. Some of you guys asked for it. Here it is.

While the Martin Mars was the biggest flying boat to ever go into production there are bigger examples. The Saunders-Roe Princess was over 30 ft longer, had a longer wingspan by almost 20 ft, and it was considerably heavier. Only one Princess ever flew which happened first on this day, August 22, 1952. This was too late to become a commercial success. Land-based jet airliners were the future. Here is the Princess compared with Philippine Mars scheduled to arrive later this year.

Fascinating story. THe plane, the buildiers, the companies and successors, etc.,
The S-R Princess was powered the the Bristol Proteus (six of them, four with two propellers), the first mass-producted gas turbine turboprop airplane engine.
An innovative but ultimately a failed design, and not useful (gas turbines of THIS design - too heavy, underpowered, complicated design, unreliable mechamicals, gas hogs, etc ) for aircraft propulsion.
Variants of THIS gas turbine found more land-based usages ( e.g., boats, gen sets, tanks, etc) -- but thats another thread.

Like #2.474 above, from right to left would be moving from "cab to cowcatcher", another steam locomotive firebox/boiler, before moving on in the assembly process.
Obviously, before its all tricked out with pipers, valves, etc and mounting to the "truck",

With Diesels coming on string in the '40s, I can't believe that someone would still build a new Steam Engine in 1943. It couldn't have had much of a service life.

Dunno if #2,474 was a new build, or a refurb, I suspect some form of the latter (Shorpy.com)
My posted #2,475 was like a decade earlier, so asserted to be a new build (Construction of a railroad engine. Ready to ship to assembling shop)
in hindsight, the industry stayed in steam - as primary prime movers - TOO long. At the time of any transition, the new thing is resisted. Or, the threat of the new thing to an incumbent techology is not clear,
Dozens of examples in the industrial age (roughly mid 1800's until this very minute). 50 years from now theyll be saying ssame thin about us and ICE's.
I think the last new steam locomotive builds lasted till the 1950's in the country. That would have been late .. even viewed back then. By then, the deisel electrics weren't coming ... they were HERE.

With the old tub removed, the Big Muskie stands on its feet. Reinforced steel bracing is added for additional stability.
