Ok lost 3. My 'tricky' memory tells me that they lost more than that number of SB2C
OK I've now found the details. 240 aircraft launched. 14 aborts returned to carriers. 20 lost to AA and fighters around the 4 groups of Japanese ships spread over a distance of 30-40 miles. Just after time of launch the Japanese fleet was reported 60 miles further west than previously believed, giving a run in of 300-330 miles (sources vary)and a return of an estimated 250. Once the Japanese fleet was located, the strike itself was over in about 20mins.
95 F6F Hellcats (some armed with bombs)
26 SBD Dauntless
51 SB2C Helldiver
54 TBM Avengers (sources vary as to how many carried torpedoes. Anything from 4 to 21)
The losses from ditching or deck crashes were around 80 aircraft per one source I have, but another source gives 76 broken down as follows:-
14 F6F (another source says only 6)
4 SBD
35 SB2C
23 TBD (another source says 28)
BUT
A few points to bear in mind:-
1. The launch process itself took at least 10-15 minutes plus time to form up the air groups before departing for the target (normally about 20 mins, but procedures were changed to shorten this to save fuel). Time, and fuel was saved by not waiting to co-ordinate attacks. Launch order would generally be F6F then SBD/SB2C then TBM.
2. The carriers had to reverse course and increase speed to 22 knots and run
eastwards into the wind
and away from the Japanese fleet, before landings could begin.
3. The landing on period stretched over 2 hours.
Taken together with 2 above, the gap from the Japanese fleet
increased by some 44 nautical miles (50 statute miles) during the landing on process. That can't have helped. Also, note the difference between the actual strike time c20 mins) and the landing on time (2 hours). It shows just how the strike force became strung out on the way home.
4. Some units, including CAG-2 on Hornet, had agreed before take of that, as the strike was at extreme range, in the event of aircraft running short of fuel then groups of aircraft should ditch together with the crews tying their life rafts together to increase the likelihood of rescue. I don't know if it actually occurred that way at all, but it was in the Action Report prepared after the event by CAG-2.
5. Some of these aircraft had suffered battle damage or had wounded pilots, so might not have made it back anyway.
6. As noted previously the two SBD equipped VB squadrons were experienced, having been aboard their carriers for longer than those equipped with the SB2C units.
So there are a range of factors that would have affected just what distance / time individual aircraft would have had to fly during the mission, before considering things like individual aircraft engine performance and pilot skills at ekeing out that fuel.
By dusk on 21 June a massive rescue operation by TF58 ships and floatplanes and PBMs meant that all bar 16 pilots and 22 aircrew were recovered.
