The first 345 aircraft of this contract (serials 44-84992 to 44-85336) were designated P-80A-1-LO. Some of them were powered by the 3850 lb.s.t. General Electric J33-GE-11 turbojet, the production version of the I-40 which had powered the XP-80A and the YP-80A. Others were powered by the Allison J33-A-9, a version of the same engine built by the Allison Division of the General Motors Corporation.
The next 218 aircraft in the contract (44-85337 to 44-85941 and 45-8301 to 45-8262) were built as the P-80A-5-LO production block and differed by being equipped with the more powerful 4000 lb.s.t. Allison J33-A-17. The -5 also introduced a boundary layer control splitter plate inside the air intake. The landing light was relocated from the nose to the nosewheel landing gear strut. Later, the initial production P-80A-1-LOs were retrofitted with the uprated Allison engine during routine engine overhauls.

44-83028 and 44-83029 were shipped to the Mediterranean. They actually flew some operational sorties, but they never encountered any enemy aircraft.

They were not "YP-80's", they were P-80A's.
I'm seeing YP-80A's in service during WWII.
There were thirteen YP-80A's built with serial #'s
44-83023
44-83024
44-83025
44-83026
44-83027
44-83028
44-83029
4 4-83030
44-83031
44-83032
44-83033
44-83034
44-83035
44 -83026 and 44-83027 were shipped to England, 026 crashed on its second flight in England and 027 was modified by Rolls Royce to test the Nene engine.
44-83028 and 44-83029 were shipped to Italy for combat service tests.
All these were powered by the GE I-40 engine which became the GE/Allison J33 this engine (I-40) produced 4000lbs thrust.
The first 20 or so were designated YP-80, the next 25 were P-80A's, all delivered before VJ day. By the end if 1945 there were over 550 delivered P-80A's, plus the original 20 or so YP-80A's. The first 345 P-80A's used the General Electric J33-GE-11 or identical Allison J33-A-9 turbojet engine, developing 3850 lbs static thrust.

3. in fact YP-80A's.They were not "YP-80's", they were P-80A's.
I believe some variants of the P-80 had water-methanol injection that would raise the thrust over 5000lbs. I'm pretty sure it wasn't available on the YP-80's used during WWII.
