In 1940 the solution to German U-boats off the US east coast was deemed
to be giant long-range flying-boat bombers. Boeing was the obvious
builder with its track record of the prewar "Clipper" airliners and the Navy
ordered 57 to start with. Boeing built a whole new plant at Renton by Lake
Washington to build the Sea Ranger. The XPBB-1 prototype flew in July
1942 and was the largest twin-engined aircraft built to date, but the
experiences of the Pacific War saw the War Department completely revise its
strategy in favour of land-based bombers. The Sea Ranger programme was
cancelled and the Renton plant was swapped with the army for one in
Kansas. Renton subsequently built over 1000 B-29s and later C-135 jet
tanker/transports and 707 airliners. The solitary Sea Ranger never flew a combat mission before it was mothballed and scrapped.

| Rob Milford, milford55=hotmail.com, 02.12.2010 Bob Robbins was the prime test co-pilot for this a/c, told me many times of the Navy delivery flight. The Navy Captain came in, Bob told him to sit in the left seat, and he flew from there, since Bob didn't have any left seat time! Bob allowed that there was one ofther issue: This used the same engine as a B-29, and the big bird needed 'em more. And, it ended up being called the "Lone Ranger" since it was 'one of as kind'. Never saw the color pic above..very nice! | | steve, stevelewisnewport=yahoo.co.uk, 28.11.2008 With a max range of 6300 miles @ 158 mph, a incredible flight duration of nearly 40hrs, was this potentially the longest flight duration of a standard production aircraft, a world record possibly | | Jim Medley, jmedley1341=msn.com, 27.05.2008 This plane looks a lot like a USN ASW plane flown by VP 49 out of Burmuda during Cuban crises. It was called the P5M Marlin. If you have info please email to jmedley1341@msn.com | | Cass Phillips, cassphillips=cox.net, 26.04.2008 The hull of this plane looks a lot like the PBM. |

PROFILE
FACTS AND FIGURES© Surprisingly for such a large flying
boat, the XPBB was twin-engined.
Defensive armament was only
four machine guns but the bomb
load was greater than a B-29's. © The XPBB-1 s wing was based on
that of the B-29 Superfortress. Some
of rhe aerodynamics were inherited
from Boeing's Model 314 Clipper. © There was a plan to use special
barges to catapult launch the Sea
Ranger so as to increase the already
long range, but this was never tested.
