Funked, don't use one number out of context. Start a couple of paragraphs up from where you grabbed that number.
On the issue of when it entered combat, FYI the Mustang started reaching 8th AF units in Jun 44 (source America's Hundred Thousand).
- "Service flight tests of the La7 began in mid september 1944, and were conducted by the 63rd Guards Fighter Air Corps at the First Baltic Front for one month. Thirty La7's, mostly built by the Moscow aircraft production plant, were assigned to the tests. <snip> During the tests, the regiment made 462 sorties, during which 55 enemy aircraft were shot down for the loss of eight La7s (half of which was non combat) and three pilots."
On the issue of numbers, your being very misleading, when you quote 291.
- During October and November 1944 La-7s began to be used widely on all fronts. <snip> More than 2,000 La7's, mainly built by major Plant No. 21, were sent to the front up to the wars end. <snip> By Early 1945 there were 398 La7's in front line air force units, and 291 were combat ready. This was equivalent to about 6% of all serviceable fighters. By the end of the war this had increased to 15%. <snip> A total of 5,753 La-7s were built by the three plants up to the wars end.
Now, I don't have numbers for the P-51D when it comes to "deployed in front line service" or "Serviceable on XXX date" (if anyone has please share them), but the total production up to wars end was 8,056.
Honestly, Just how many of those were actually in front line service, AND combat ready? I dont' know myself, but I will leave up to someone else to research.
BUT if you want to compare like numbers to like numbers its
5,753 to 8,056, not 291.
For comparisons purposes with other AH American aircraft (all production numbers from America's Hundred Thousand):
P-51D 8,056
F6F-5 6,436
La-7 5,753
P-47 5,264 (D25's thru D30)
P-38L 3,923
F4U-1D 2,800 (including FG-1's)
So if you use the same type of data, you will see that the La7 was as numerous and important as many of the US Models in WWII.
