DH.98 Mosquito
A dedicated Mosquito website is under construction providing comprehensive histories of each aircraft and aircrew casualties. Online late 2025.
The production list contains 7785 entries against the generally quoted total of 7781. My list includes 10 T.III supplied new to Turkey (THKv serials 6601-6610, Fairey c/ns 533-542 respectively).
There is dispute over whether they were new built or refurbished. Delivery via Fairey would suggest they were refurbished but there is no record of T.III machines being sold back to DeH or Fairey on the history cards.
HJ734 and HX897 were built but crashed before delivery (Mk.VI).
HX849 and HX850 were probably not built (Mk.VI).
MM311 (PR.XVI) has been reported as not delivered. RAF records show 'conv WS.VIII' indicating it went to the USAAF as an F-8. It was in fact one of the H2X 'Mickey' machines.
MT480 (NF.30) has no delivery record.
NS677 (PR.XVI) has been reported as not delivered. RAF records show 'conv WS.VIII' indicating it went to the USAAF as an F-8. It was in fact one of the H2X 'Mickey' machines.

Construction numbers
UK production:
C/ns ran from 98001 to 98999 and then from 981000 onwards
The first 80 aircraft (W4050-W4099 and DD600-DD629) has c/ns running in sequence from 98001 to 98080.
Thereafter c/ns were not allocated in order.
Other known c/ns are:
DZ411=98421 (to G-AGFV)
HJ680=98723 (to G-AGGC)
HJ681=98730 (to G-AGGD)
HJ718=98740 (to G-AGGE)
HJ720=98742 (to G-AGGF)
HJ721=98743 (to G-AGGG)
HJ723=98750 (to G-AGGH)
RG233=982827 (to N9870F)
RG300=983157 (to N9871F)
RK952=984597 (Brussels Museum)
PF670=PAC.LF30 (Percival Aircraft Luton built)
Australian production:
Separate c/ns were allocated to Australian produced aircraft starting at DHA3001
The Australian aircraft were subsequently modified to PR41 standard and new c/ns were given commencing at DHA3213.
The new c/ns appear to have been issued in the order that conversion was undertaken
The only known c/n is DHA3236 which applies to A52-210
Canadian production:
A separate c/n sequence was also applied by mark to Canadian aircraft as follows:

Discrepancies
Canadian reconciliation:
The Canadian total is 1133 despite a well-known photo proclaiming the completion of the 1134th aircraft.
Many references list 1066 aircraft. To reconcile to my total:
1. Add KA442,443,445-449 All have RCAF history cards
2. Add KA451-540 (90) Aircraft built post-war and supplied to China
3. Query KA928/9 (-1) most sources say neither produced and no RAF card for either.
4. Delete KA898-927 (-30) not built.
5. Add KA441,444,450 (3). All built per British Military serials book and have RAF history cards
6. Delete KA287,377 (-6) Not built per British Military serials book and no RAF history cards
But query 287 and 377 as some sources list as built.
This gives a new total of 1133.
Alternatively include KA928 or 9 to give 1134.
UK production:
1. Add VP342-355 Mk T.III aircraft built. All have history cards.
2. Add TH976 History card exists.
3. Add DZ239,539 T3/FBIV History cards exist. Batch doesn't add to round number without them.
4. Add TS444,449 TR33 prototypes
5. Deduct RS581 No card. Not included in any serials book.
6. Add MT500 NF30. History card exists. Batch doesn't add to round number without it.
7. Add HJ824-833 FBVI. History cards exist. Batch doesn't add to round number without them
8. Add HJ851 T3. History card exists. Batch doesn't add to round number without it
9. Deduct HR536-538 No history. Batch doesn't add to 500 with them
10.Add HR648-649 FBVI History cards exist. Batch doesn't add to round number without them
11.Ignore HX849-850 Reported as collided on test flight (confused with HJ734/HX897) but weren't built.
