https://en.wikipedia.org/wiki/Republic_P-43_Lancer
The Republic P-43 Lancer was a single-engine, all-metal, low-wing monoplane
fighter aircraft built by Republic, first delivered to the United States Army
Air Corps in 1940. A proposed development was the P-44 Rocket. While no
world-beater as a fighter, the P-43A had a very good high-altitude performance
coupled with an effective oxygen system. Fast and well-armed with excellent
long-range capabilities, until the arrival of the P-38, the Lancer was the only
Allied fighter capable of catching a Japanese Mitsubishi Ki-46 "Dinah"
reconnaissance plane at the speeds and heights at which they flew. In addition,
the P-43 flew many long-range, high-altitude photo recon missions until replaced
by F-4/F-5 Lightnings (P-38 variants) in both the USAAF and RAAF.
The Seversky Aircraft Company, which in 1939 changed its name to Republic,
constructed a range of private venture, one-off variants of its P-35 design,
featuring different powerplants and enhancements, designated AP-2, AP-7, AP-4
(which flew after the AP-7), AP-9, XP-41. The series included a carrier-based
version designated the NF-1 (Naval Fighter 1) that was also built. The most
significant of these was the AP-4, which served as the basis for future
Seversky/Republic aircraft. It featured fully retractable landing gear, flush
riveting, and, most significantly, a Pratt & Whitney R-1830-SC2G engine with a
belly-mounted turbo-supercharger, producing 1,200 hp (890 kW) and good
high-altitude performance. The turbo-supercharger had been refined by Boeing as
part of the development program for the B-17 Flying Fortress, and the improved
performance it offered was of great interest to other aircraft manufacturers.

The Lend-Lease aircraft were delivered to China through Claire Chennault's
American Volunteer Group, the "Flying Tigers". Pilots involved in the ferrying
flights commended the P-43 for its good high-altitude performance compared to
the Curtiss P-40, good roll rate and a radial engine without a vulnerable liquid
cooling system. Apparently, several AVG pilots asked Chennault to keep some
P-43s, but the request was denied due to the aircraft's lack of armor or
self-sealing fuel tanks. In addition, the turbo-supercharger proved unreliable
and the "wet wing" fuel tanks leaked constantly. In June 1942, Robert L. Scott,
44,000 ft (13,000 m), attesting to the strengths of this aircraft. The P-43
performed poorly in combat in the hands of the Chinese Air Force against Japan
due to its great vulnerability; it was replaced by other aircraft in early 1944.
Rudimentary protection added on the P-43A-1 was insufficient. In addition, the
P-43's R-1830 engines were in high demand for the Douglas C-47 transport,
effectively grounding the surviving aircraft.
The USAAC considered the P-43 and its variants obsolete from the start and used
them only for training purposes. In fall 1942, all surviving USAAF (transitioned
from USAAC in June 1941) P-43s were redesignated RP-43 indicating they were
unfit for combat. Most of the aircraft that were not sent to China were modified
for photo-reconnaissance duties and used for training. Eight P-43s (four
P-43a-1s and four P-43Ds) were loaned to the Royal Australian Air Force in 1942
and served with No. 1 Photo Reconnaissance Unit, based at Coomalie Field, 60
miles south of Darwin in the Northern Territory. The RAAF flew many long range,
high-altitude photo reconnaissance missions before the six survivors were
returned to the USAAF in 1943.
