[bada]

Pullman became Silverplate became Saddletree (Baugher says Saddleback) in May 1947 before all of the final batch of B-29 had been converted, in turn Saddletree became part of the Gem program.

Constituted as 509th Composite Group on 9 Dec 1944 and activated on 17 Dec, Wendover Field, Utah, 17 Dec 1944-26 Apr 1945; North Field, Tinian, 29 May-17 Oct 1945; Roswell AAFld, NM, 6 Nov 1945-16 Jun 1952.

46 B-29 built before the end September 1945 reported modified to Silverplate status, by November 1946 four had been lost, 19 more modified in 1947 from exiting stocks as project DOM-515. Then came the B-50 and B-36 modifications. Looking at Baugher, the aircraft cards and delivery logs gives the following list of 46 done by end 1945, block, serial, acceptance date,

As units were rotated front/rear areas they could give up or gain the latest equipment. First Spitfire XVIII squadron service August 1946.

Hi,
The global numbers are one thing, operational airframes are another.
Here, the stats, for the Spit14, from production start until 10thMay45 (end of war in the ETO), what happened after this date wasn't important for me.
This is based on the "Spitfire production list" available freely on the web and also used i some books.
MU= Maintenance Unit (Factory Repair or repair hub)
SQ= Assigned to Squadron
SoC= Struck of Charge (airframe not usable/destroyed, set officially by the RaF)
India= airframes send to india
Awaiting Delivery: Airframe put in MU after Production waiting for assignment to squadron
Test= Airframes send to Test Centers for technical evaluations
Total Dead= total number of SoC Airframes.
Values are valid on the 10th/20th/Last day of the month.
Some errors could occur as the list is not always precise for each airframe, but it gives a good idea.

Number of airframes assigned per squadron ( with "Group Units" that served as immediate reserve pool included):

Mk XIV has the wing from the Spitfire VIII, which is basically the same as the previous versions (IX, V, etc.).

Mk.21 - Mk.24 have the revised wing with slightly different plan form and stronger structure, and fully enclosed landing gear.

Mk.22 was the same as the Mk.21 but with the teardrop canopy and cut back fuselage. The larger fin and rudder of the Spiteful were introduced part way into production, with most being fitted with them.

Mk.23 was experimenting with the wing, not put into production.

Mk.24 was Mk.22 with additional fuel tanks.

What is the difference in a marque? The total of all differences between all the Griffon engined spitfires were probably less in real terms than all the differences on a Spitfire Mk I from first production to last. Certainly less than all the changes made to a Hurricane Mk I yet they are all classed as Mk Is.

The performance of Hornet seem so much better than I expected. Speed is competitive with even P-51H, while climb rate, power loading, wing loading are even better than prototype like spiteful XVI and XP-72
Performance of the de Havilland Hornet:
Sea level speed: 392 mph ( 630.8 km/h)
Top speed: 472 mph (759 km/h) at 22,000 ft
Climb rate: 5450 ft/min ( 27.68 m/s) at sea level
take 4 min to climb to 20,000 ft
Engine horsepower:
2 x Merlin 130/131 engine with 2,070 HP each at WEP
Normal take off weight: 16,100 lbs (7302.8 kg)
Wing area: 33.538 m2 ( 361 ft2)
Wing loading: 217.74 kg/m2
Power to weight: 0.566 hp/kg ( 0.257 hp/lbs)
Weapons:
Four 20 mm cannon

That is a lot of good work creating the Spitfire charts. For comparison, Spitfire XIV from the RAF Census AIR 20/1871, file ends in June 1944, figures as of end of month. Spitfire XIV first official production October 1943. Cat E figure is cumulative, other figures are strengths.
