Its probably a post I made.
Data is from the book:
Aircraft Vulnerability in World War II
A. H. Peterson
Rand Corporation, 1950
Document number # RM-402
This book can be ordered by calling 1-877-584-8642
Or emailing order@rand.org
If you do order it, you need to tell them that you want a bibliography. There is some very interesting looking stuff in the bibliography.
Some sample information follows:
From page 53
Aircraft lost to hit ratio for hits on components (F4U, F6F, SB2C, TBM, Note: all radial-engined)
From Japanese Aircraft Fire – Sept 44 –August 45
Hit location # hit #lost Loss %
Propellor 9 0 0
Powerplant 37 23 62.2
Structure 215 23 10.7
Pilot/flight controls 97 74 76.3
Surface Controls 27 0 0
Oil System 27 23 85.3
Fuel System 30 24 80.0
Hydraulic System 35 21 60.0
Electrical System 6 0 0
Other 18 5 27.8
Total 501 193 38.5
If I arrange the causes of losses in weighted order:
Hit location #lost % cause of total losses
Pilot/flight controls 74 43.0
Fuel System 24 14.0
Powerplant 23 13.4
Oil System 23 13.4
Structure 23 13.4
Other 5 2.9
