P-38L-5-LO had strengthened racks underneeth specificly for the purpose of carrying 2000 pounders and/or 300 gallon drop tanks (300 gallons of gas weighs about 2500 lbs)
F4UDOA - is that 1st pic Korean War era? - i've read F4U-1d carried bombs on underwing racks in addition to centerline point for D/T. i've also read that the AU-1 could carry 8500 lbs total (but probably not off the carrier deck) - 2nd pic looks to have a 1944 number on it, but that field looks too nice to be a combat ops field - Wright field maybe?
