I just double checked, he numbers I gave are a bit muddied-up, too. I've two Pilot's Handbooks for the Mosquito, one for the FB.6 (Fighter-Bomber) from 1950, and one for the various single-stage Merlin Night Fighters, published in 1945. The numbers I quoted were from the FB.6 handbook, and the NF.12 handbook is different. The NF.12 book lists best cruise as 220 mph IAS, which is nudging 330 TAS at 25,000'. and 360 TAS at 30,000'. It's possible that the FB.6 numbers are for an airplane carrying external bombs and rockets, but it doesn't say. Sounds like the time to add the information from the book Mosquito by Sharpe and Bowyer. The FB6 used Merlin 21/22/23/25, the NF12 merlin 21/23. Appendix 8, performance of the B35 (merlin 114) versus the FB6 (merlin 25). B35, 22,000 pounds, bomb load 1,500 pounds including 2 x 500 pounds bombs under the wings, 539 gallons of fuel, still air range 1,600 miles at 25,000 feet at 300 mph TAS, 1,250 miles at 37,000 feet at 375 mph TAS. Top speed 425 mph at 30,500 feet. FB6 21,700 pounds, bomb load 1,500 pounds including 2 x 500 pounds bombs under the wings, 453 gallons of fuel, still air range 1,120 miles at sea level at 250 mph TAS, 960 miles at sea level at 296 mph TAS. Top speed 378 mph at 13,200 feet. The Merlin 72/73 or 76/77 versions (VII, IX and XIV) outward recommended cruising speed 220 mph IAS, economic cruise in clean condition was 295 mph TAS at 20,000 feet and 350 mph at 30,000+ feet, maximum continuous cruising, clean, 349 mph TAS at 20,000 feet, 378 mph TAS at 30,000 feet. For the merlin 21/22/23/31 equipped versions maximum continuous cruise was 341 mph TAS at 20,000 feet but this fell to 329 mph at 25,000 feet, I assume in clean condition. Again outward bound recommended cruise was 220 mph IAS at around 25,000 feet. The return flight recommendation was for around a 5% reduction in cruise speed compared with outbound, 210 mph IAS.

I can't help but compare it to the B-26 which got its best range at 180 IAS loaded with steel plate armor and bristling with machine guns and carrying a crew of 6. Take off the armor, take off the guns and top turret and cut the crew to two and the B-26 may well have outperformed the Mosquito by a large margin.. But, as you say, an unarmed and unarmored B-26 would have been of "no value". OTOH, the Brits found the Mosquito of some considerable value in a variety of roles. As did the USAAF which acquired quite a number of mosquitoes. Cheers and all, |

Subject: #1 Jet of World War II
From: (The Revolution Will Not Be Televised) Date: 7/4/03 11:41 AM Pacific er, if you did, and you served in the RAF in the 2nd Tactical Air Force at the time in question, please pass on the information. No. I served in the 344th Bomb Group, 494th Bomb Squadron of the 99th wing of the 9th Air force, But you see the Luftwaffe was a very democraticc organization They didn't restrict their hits to the RAF 2nd Tactical Air Force. They would hit anybody any time. , The Luftwaffe was an equal opportunity hitter. .. Arthur Kramer Visit my WW II B-26 website at: http://www.coastcomp.com/artkramer |

No. I served in the 344th Bomb Group, 494th Bomb Squadron of the 99th wing of the 9th Air force, So you didn't serve in 2nd TAF or experience operations on the 2nd TAF area of operations? If n I would be interested in your experiences with the 2nd TAF. Y'know basic simple stuff .Missions flown. Targets attacked. Y'know, simple stuff.

Hi the Meteor was used to shoot down V1 missiles it was quite good at it! too so it was band from front line service i think until the end of the war. True - it's straight line speed was perfect for the running chase. In this footrace, its lack of maneuverability was not a hindrance. Later marks of the fighter were quite an improvement and by all accounts corrected their earlier faults. v/r Gordon |

The Jerrys may have had many of aviation's "firsts" with their jets but lacked anything good enough to last beyond a few years. The Meteor lived well beyond the war and established itself quite well. Too bad you Yanks had such misfortune with that horrid XP-59 and troublesome XP-80 aircraft. Keith, you are not really being fair to the US jet a/c you mentioned. Remember that the P-59 was ordered as a "proof of concept" a/c, to demonstrate that US forms could adapt to the new technology with respect to manufacturing procedures, etc. The P-59 was outfitted with direct copies of a "weak" (so to speak--1st generation) Whittle turbojet. Because of its experimental nature, it was terrifically overbuilt (and hence noticeably overweight). If you can locate the performance figures for the 1st batch of P-59s and compare them to the same for the first batch of "Meatboxes", you will find close similarities. Later P-59s had more powerful engines, but featured little or no change in weight because no effort was expended in productionizing the bird. In short, the P-59 was never intended for combat use. There was no "misfortune" involved with the P-59 for the USAAF, although Bell Aircraft may have missed the boat with a too-conservative approach to its design and development. Bell ignored suggestions to "prove the concept" by simply fitting a pair of the Whittles to the undersurfaces of a P-39's wings, then asking for a contract to develop a serious fighter. I believe also that you mischaracterize the P-80. It was constructed in a remarkable short time during 1943 to take an Halford engine, then in short order essentially re-designed and enlarged in order to take a more powerful engine, also adapted from the British. The major "problem" associated with its early use was overconfidence on the part of the first pilots who flew them. A second was a flaw in the fabrication of early turbine blades, which came from the factory with impurities near the tips which weakened their structure, and hence would fail at normal operating temperatures. Another flaw was the fuel system, again drawn from British practice, which took power via gears from the powerplant. It was discovered that at max throttle, such as used at takeoff, this system could not always guarantee sufficient fuel flow sustain combustion, leading to flameouts; a simple solution was to fit an auxiliary fuel pump, which was supposed to be engaged by the pilot prior to takeoff, and during the landing approach, as a precaution. On a number of occasions, crash investigation discovered that the pilot had failed to engage the aux pump. Meeting and overcoming unanticipated development problems is part and parcel of making a warplane operational. The contrast in time-frames between the Me-262's initiation and its "readiness" for combat and that of the P-80's is remarkable. By 1945, the P-80 demonstrated docile engine characteristics, the ability to operate at 39-40,000 ft altitude, reliable powered ailerons, no controllability problems, high overall quality control, an efficient laminar-flow wing, and the ability to take off on a mission, climb to cruise altitude, fly 500 miles, drop tip-tanks, and fight at 100 per cent power for 15 minutes before having to return to base, with enough fuel remaining for one missed approach. The basic design, hailing from 1943, proved adaptable of taking engines of from 4,000 to in excess of 6,000 lbs thrust; of being the basis for a very successful two-seat land-based trainer; the basis for a two-seat radar-equipped rocket-firing all-weather interceptor; of being adapted for carrier-borne pilot training; and of accepting afterburning for increased acceleration and climb. The F-80 gave excellent service in the Korean conflict, obtaining the first victory in all-jet combat, downing a Soviet-built Mig-15. Kenneth Williams Actually the P-80, in its various iterations, served quite long and well. I'm not sure, but I think the Bolivian Air Force still has (or had until very recently) its T-33s in service. -- __________ ____---____ Marco Antonio Checa Funcke \_________D /-/---_----' Santiago de Surco, Lima, Peru _H__/_/ http://machf.tripod.com '-_____|( remove the "no_me_j." and "sons.of." parts before replying |

the P-59 was never intended for combat use. Hap Arnold certainly thought he was getting a combat airplane in the P-59A (not to be confused with the never-built P-59). If he'd wanted a test-bed, he could have ordered something on the order of the Gloster Carter Farter or the little Heinkel. This thread is a bit silly. There was only one jet fighter in WWII, and that was the Me 262. Getting there too late for combat (P-80) doesn't count. Chasing V-1s (Meteor) doesn't count. Being deemed unsuitable for combat (P-59A) doesn't count. The only thing that counts is shooting down enemy aircraft. Anyone who has followed my postings on the German air force knows that I'm not a greater admirer of its war-fighting record. But in the case of the Me-262, the Germans built a handsome, innovative, and terrifying war machine. We can all be grateful that it came too late to make any difference in how the air battle over Germany worked out. all the best -- Dan Ford (email: info AT danford.net) see the Warbird's Forum at http://www.danford.net/index.htm Vietnam | Flying Tigers | Pacific War | Brewster Buffalo | Piper Cub |

That's a little unfair, they also made several strafing claims. They were too late to have any significance, but this also applies (to a lesser extent) to the 262 as you point out.
