Here's the sortie count and bomb tonnage for the B-25 and B-26: We never flew "sorties" We flew missions. Fighters flew sorties. You, fighters and everyone else flew missions that involved a certain number of sorties, effective and ineffective, and records were kept of both. If you want to know what the average effective bombload per a/c was, just counting missions isn't going to do it, because you need to know how many a/c flew on each mission for the number to mean anything; in short, you need to know the number of sorties. The figures I gave above are presumably either effective sorties (those assessed as having dropped bombs), or at least those that were officially counted (i.e. you'd crossed the enemy/occupied coast or whatever the criteria was in the particular theater/timeframe).

No sorties because you need to know how many a/c flew on each mission for the number to mean an We flew 56 Marauders on every mission. Max effort every time. The figures I gave above are presumably either effective sorties (those assessed as having dropped bombs), or at least those that were officially counted (i.e. you'd crossed the enemy/occupied coast or whatever the criteria was in the particular theater/timeframe). Yeah, that was a bad habbit of ours. We always crossed into enemy territorry and dumped 4,000 pounds of bombs all over them. We called these missions.

You, fighters and everyone else flew missions that involved a certain number of sorties, effective and ineffective, Missions that involved sorties???? What does that mean?. I flew all missions. No sorties. As explained by another poster, a sortie is one flight by one a/c. X number of a/c in a squadron, group or what have you can all fly a single mission, which will count as X number of sorties total. Think of a sortie as the aircraft equivalent of a man/day. If you have a job that is supposed to take 10 man/days to complete, then to do it you can (ignoring any practical difficulties that might preclude some of the combinations) either use 1 man for ten days, 2 men for 5 days, 5 men for two days, or 10 men for one day. Sorties work similarly: 1 a/c flying ten missions, 2 a/c flying 5 missions, 5 a/c flying two missions, or 10 a/c flying one mission, all count as ten sorties. because you need to know how many a/c flew on each mission for the number to mean an We flew 56 Marauders on every mission. Max effort every time. Which is 56 sorties. But medium units didn't always fly 56 a/c. At least in 1943, it was usual to fly 36 a/c group formations (group UE was increased later) in the ETO, and fighter and heavy bomber units had different establishments and flew different formations consisting of different numbers of a/c. the typical heavy bomber group in 1943 would put up between 18-24 a/c for a single mission, i.e. 18-24 sorties. The figures I gave above are presumably either effective sorties (those assessed as having dropped bombs), or at least those that were officially counted (i.e. you'd crossed the enemy/occupied coast or whatever the criteria was in the particular theater/timeframe). Yeah, that was a bad habbit of ours. We always crossed into enemy territorry and dumped 4,000 pounds of bombs all over them. We called these missions. Not sorties. Art, not every a/c that took off crossed into enemy territory. There are inevitably aborts for various reasons. Depending on where the abort occurred, it might or might not count towards completing the tour requirement. The USAAF usually defined an effective sortie as one which dropped bombs on a target. So, for instance, on the Regensburg-Schweinfurt Raid, the 4th Bomb Wing dispatched 146* B-17s on VIIIth BC Mission Number 84, to Regensburg, or 146 sorties (*sources are a bit schizophrenic, as most say 146, but detail 147). Of that number, 11 aborted over England or the North Sea for reasons other than enemy action, but four were replaced by airborne spares, making 139 that crossed the coast. None of the crews of a/c which aborted for these reasons prior to crossing the Dutch coast were allowed to count this mission towards their tour. By the time they got to Regensburg, fourteen more had been shot down, two more had left the formation, dumped their bombs and were hoping to cut the corner and catch up, and one a/c had remained in formation but had had to jettison its bombs. The crews of these a/c were allowed to count the mission towards their tour, but none of these sorties were counted as 'effective', because they didn't/couldn't put bombs on target. The remaining 122 a/c were all able to bomb, so 4th Bomb Wing recorded 146 sorties dispatched (not counting spares), but only 139 combat sorties consisting of 122 effective and 17 ineffective sorties. Being able to bomb a secondary or tertiary target or a target of opportunity, rather than just jettisoning bombs, would usually be counted as an effective sortie (depended on the time and theater); a/c which were unable to bomb an allowed target for any reason would count as an ineffective sortie.

Compared to the original design wingspan (widely cited as 112 feet) 135 ft. isn't such a stretch. Compared to the Stirling production wingspan of 99 feet, it is ;-) But it sure would be nice to see the predicted performance for a Stirling with a 112 foot span, high aspect ratio wing. That wing would be up in B-24 territory. Oh well, I can dream. Guy |

wrote: And the Wellington was upgraded to become the Warwick.... Have you seen the thickness of the Stirling's existing wing? Nothing like extending the tips to lower the overall t/c ratio. Yes, but those wings needed an Atkins diet or something. They're almost as thick as the fuselage. Even moving the tips out for greater wing area is going to leave it struggling with poor engine output at altitude and serious airframe weight issues. The engine output should be no worse than the Halifax III, but I grant you the weight issues. OTOH, the Stirling seems like it was quite strong, so a boost in MTOW may have been possible. Actually, reducing the weight might have helped more to raise the ceiling, and you won't be getting many Hercules XVI engines until 1944 as the Halifax production will eat them up. You might as well stick to using them pretty much as is as an interim type, and get another ten squadrons to increase the short-penetration supporting missions along with the six-eight squadrons of 2 Group. They can then re-quip with the B-24 over time, after gaining daylight experience during the supporting ops. Just don't ask me to fly in them.... [snip Sabre-engined gibbering] [B25 bombload] Personally, I wonder if your source that claimed 2 x 1,000 'and' 4 x 500 should have read 'or', as that would fit better with the claimed bomb bay capacity in several sources. It wouldn't be the first time that has happened. Agreed, and I will check the Squadron ORBs when I get the chance. Any American stats to compare with this? You think the Good Old Days on Usenet (as you define them) are gone? A quick skim of posts on this or most any other forum will show that, as the Republican Party's semi-official theme song says, Happy Days are Here Again! But then, you've never been there and done that, you're just another wannabe ;-) And if you'd ever seen Serdar Argic strafing an unprotected and immobilized newgroup with .50 calibre-crosspostings with your own eyes, maybe your reading would be different. We never made posts in those days, just threads. The time was this group once had real veterans like Orville and Wilbur Wright conducting their flamewar with Langley and Curtis, and now they've been driven off by the wannabes.....[tirade continued ad nauseam].
