Learned Something New

[Crazy]

today. Found out what the designations for American fighters mean:

"P" stands for Pursuit, a designation used for fighter types between 1925 & 1947, though this changed in 1947 when the "F" for Fighter designation entered use.



"51" means the the aircraft was the 51st pursuit type to be built.

"D" The fourth main variant of the Mustang which included the 1,490hp Packard V-1650 Merlin engine, six gun main armament, and the teardrop canopy.

"20" This is the Block Number. These numbers ran in fives as minor equipment changes were implemented.

"NA" means that the aircraft was built at Inglewood, California, the other designation "NT" denotes an aircraft built in Dallas, Texas

cool i already knew about the pursuit bit but i didnt know about the other stuff

[plan_D]

I knew all of that but, what can I say? I remember you had to get told what the P means by LG.
Just to add to the list for production designations; RE, Republic Farmingdale; RA, Republic Evansville; CU, Curtiss-Wright at Buffalo.

LO- Lockheed, Burbank
VN- Vega, Nashville

You mine find this interesting as well. American engines were designated by a letter and then a series of numbers (V-1710, R-2800, etc.). The letter designated the type of engine (V for inline 'vee' engine, R for radial) and the numbers were the capacity of the engine in cubic engines.

the numbers were the capacity of the engine in cubic engines.

now that's what you call spam................

[cheddar cheese]

[Lightning Guy]

Cubic inches. They sound similar so (as crummy as it is) that's my excuse.

it's better than anything C.C. could come up with....................

[cheddar cheese]

im fine with that cos any insult to me is an insult to you too, you are the inferior of the two of us after all

[the lancaster kicks ass]

back on topic, i gonna hint as guess that the "B" as in "B-52" & "B-36" means bomber??

[plan_D]

Thanks for telling us that, Lanc.

I'll probably get some of these wrong but; P is Pursuit, F is Fighter, B is Bomber, A is Attack, PR is Photo-Recce, AEW is Airborne Early Warning, AWACS is Airborne Warning and Control System...I know the last two were modern.
I've missed some there...the F could get confusing because in World War 2 the Americans didn't have F for fighter, they had the F-5 which was a recce Lightning but I don't know what the F stands for on that...

[Lightning Guy]

I'm not sure that it stood for anything. There were also F- models of the A-20, the P-51, and I believe the B-24 but I don't remember exactly what the designations were.
