The RAAF was the second service to order the Lockheed Hudson and the most important operator of the aircraft after the RAF. For the first two years of the war in the Pacific the Hudson was the RAAF’s most important bomber and like every Allied aircraft in the Pacific in 1942 it suffered heavy losses at the hands of the Japanese.
In November 1938, after initial negotiations were conducted with Lockheed’s Australian agents, Brown & Dureau Ltd, the RAAF ordered 50 Hudson aircraft through the British Air Ministry, which had already signed an order of 200 aircraft with an option of 50 more in June 1938. These aircraft were fitted with three-bladed Hamilton Standard two-position propellers and designated the Mk I. They differed from the RAF Hudson Mk I by being powered by two Pratt & Whitney R-1830-SC3G Twin Wasp (1,200hp, 14-cylinder radial, twin row) engines in place of the Wright GR-1820-G102A (1,100hp, 9-cylinder radial, single row) engines used by the RAF. The Pratt & Whitney engine was chosen as an earlier version (R-1340-S1H1G Wasp, 600hp, 9-cylinder radial, single row) was being manufactured under licence for the Wirraway by the Commonwealth Aircraft Corporation. Armament consisted of two fixed, forward firing Browning 0.303in machine guns in the upper nose operated by the pilot and two in a Boulton-Paul dorsal turret, although the first batch entered service before the turrets reached Australia and so were armed with a gun in a flexible mount. In other respects, the aircraft were similar to the RAF aircraft.
In September 1939 a further 50 Hudson aircraft, 12 with dual controls, were ordered through the British Air Ministry. These aircraft had a stronger airframe than the Mk I and were fitted with three-bladed Hamilton Standard constant speed propellers and designated the Mk II. The RAF used the same designation. The duplication of designations was not a problem at first as the RAAF aircraft were based in Australia, Netherlands East Indies, Malaya and Singapore and the RAF aircraft in Britain and the Mediterranean, but as it had the potential to cause confusion the Australian Mk I and Mk II aircraft were subsequently designated Mk IV. These aircraft were identified under RAAF serial numbers A16-1 to A16-100 and were shipped to Australia, arriving between January and June 1940.
In March 1941 an additional 52 Hudson aircraft were ordered, then quickly increased to 146 aircraft. The first 52 were Mk IV aircraft delivered under the USA Lend-Lease program and so designated Mk IVA. Under the Lend-Lease program the aircraft were assigned US Army Air Corps (USAAC) then later US Army Air Forces (USAAF) designations and serial numbers. The Hudson would be given two USAAC designations: A-28 for aircraft powered by Pratt & Whitney R-1830 engines and A-29 for aircraft powered by Wright GR-1820 engines. The 52 aircraft were powered by the same Pratt & Whitney engines as the earlier aircraft but under its USAAC designation of R-1830-45 Twin Wasp. Only 52 A-28-LO were built, all of which served with the RAAF under serial numbers A16-101 to A16-152.
The remaining 94 aircraft were Mk III(LR) also delivered under the Lend-Lease programme and designated Mk IIIA(LR) and USAAC designation A-29-LO. The Mk III(LR) included the stronger fuselage of the Mk II, extra wing fuel tanks (hence designation as Long Range) and the addition of one retractable ventral and two beam machine guns giving it a total of seven guns and removing a blind spot below the aircraft. The Mk III was powered by two Wright R-1820-G205A (1,200hp 9-cylinder radial, single row) engines. When installed on the Mk IIIA, these engines were designated the Wright R-1820-87. These aircraft arrived in Australia between December 1941 and May 1942.
In addition, an extra aircraft found its way onto the inventory – the former RAF AE488 designated A16-222. AE488 survived the Singapore campaign when it was evacuated by a RAAF crew to Australia in March 1942 and taken onto RAAF strength – and the number of aircraft ultimately acquired by the RAAF was 247. RAAF Hudson Mk IIIA served under serial numbers A16-153 to A16-247.
There are slight discrepancies on websites and books regarding the total number of Hudson aircraft acquired by the RAAF. The www.adf-serials.com.au/ 2a16.htm notes the 247 aircraft as described above. The www.historyofwar.org/articles/weapons_lockeed_ hudson_III and IV. html notes 265 Hudson aircraft: the original 100 Mk IVs and 52 Mk IVAs, 41 Mk IIIAs (A-29-LO), 65 Mk IIIAs (A-29A-LO) and 7 Mk IVs; the latter apparently taken from an RAF order for 30 Mk IVs. The adf-serials website and Stewart Wilson are in accord regarding number of aircraft and associated serial numbers. David Vincent lists 246 aircraft and notes that A16-222 was not included in his list as it was not supplied direct to the RAAF.
After its formation on 15 September 1943, 38 Squadron’s first aircraft were all Hudson Mk IVA. After service with a range of RAAF units these aircraft were operated by 38 Squadron between November 1943 and May 1944. The squadron began re-equipping with Douglas Dakota C-47A aircraft from March 1944 and the Hudson aircraft were reassigned to other flying units.
Much of the information below has been taken from the adf-serials website. The records of each aircraft vary considerably in the level of detail available. Examples include when and at what unit aircraft were modified from the bombing to the transport role and the dates when some events occurred. Some discrepancies may be original record entry omissions or errors or subsequent transcription errors. I have also included A16-120 although the records indicated that it was allocated to 38 Squadron but subsequently not issued. I have indicated in the text the points of discrepancy with a [*], [date] or [location] for missing information and I have included a table of discrepancies and information gaps at the end of this document and will continue research to resolve them.
In the table below I have expanded the abbreviated unit names and included their locations and expanded military ranks from the adf-serials.com.au records. I have described the units No# RSU as No# Repair and Salvage Unit. These units kept that title during the period 1942-44 and then renamed to No# Repair and Servicing Unit for the period 1945-46. I have used the booklets Units of the Royal Australian Air, a Concise History to determine unit locations. I have also retained the then ‘RAAF Station’ names for major RAAF locations and the titles of the Territory of Papua (Papua) and separately New Guinea.

The information was last updated on 26th September 2014.
While there are many photographs of Hudson Mk IV aircraft there are few of the RAAF Mk IVA and I have found only two when in service with 38 Squadron: A16-122 and A16-147. Both photographs appear in David Vincent’s book The RAAF Hudson Story, Book Two. I will approach David Vincent to seek permission to reproduce these photographs or advice on their reproduction. I have included three photographs: Hudson Mk IVA A16-117 in service with 13 Squadron in 1942; Hudson Mk IVA A16-120 in service with 1 Communications Unit and assigned to the Chief of Air Staff, Air Vice-Marshal George Jones in 1944 and the former Hudson Mk IVA A16-122 in civilian rig with Adastra Aerial Surveys as VH-AGX after been converted to a Mk III following the installation of Wright Cyclone engines. Should any reader have, or know of, photographs of 38 Squadron Hudson Mk IVA aircraft we would be grateful if a copy could be provided for use on our website.

Table of Discrepancies and Information Gaps requiring further research
| Aircraft | Discrepancies and Information Gaps |
| A16-113 | adf-serials.com.au notes that the accident when the aircraft struck pine trees on landing at Sydney (Kingsford Smith) Aerodrome occurred on 14/04/42. At the above date, the aircraft was allocated to 14Sqn at RAAF Station Pearce, WA. It more likely occurred on 14/04/43 when the aircraft was allocated to 13Sqn at Camden Aerodrome, NSW. I think the adf-serials.au date is a typographic error and have used the latter date until it can be clarified.
Also, the [date] when the aircraft was at 7 Aircraft Depot for repair following the above accident and the [date] when the aircraft was received at 38Sqn is not recorded on adf-serials.com.au.
adf-serials.com.au notes the aircraft was at 7 Aircraft Depot, RAAF Station Tocumwal, NSW on 10/09/44. While this is entirely plausible, the event would occur after the allocation to 38Sqn ceased on 20/04/44 and before allocation to 1 Operational Training Unit, RAAF Station East Sale, VIC on 01/10/44. Alternately, it could have occurred on 10/09/43 to enable aircraft modification to the transport role before allocation to 38Sqn – this event is not mentioned in adf-serials.com.au. I have chosen the earlier date as the most plausible but this event requires further research.
|
| A16-115 | adf-serials.com.au notes that on 12/08/44 the aircraft was allocated for use by AOC RAAF. It is not clear which senior officer appointment this refers – could be Chief of Air Staff (?) and requires further research.
|
| A16-118 | adf-serials.com.au notes that on 08/04/42 the aircraft was at 13Sqn RAAF, RAAF Station Darwin, NT then on 23/05/42 it was at (number not provided) Repair and Salvage Unit. The closest unit was No 1 Repair and Salvage Unit, Daly Waters, NT and I have used that unit while undertaking further research to confirm. adf-serials.com.au does not indicate to which unit [location] the aircraft was allocated after completion of the above repair work.
The next event noted is a ground accident on 05/12/42 but no [location] is provided.
The [date] the aircraft was allocated to 38Sqn is not recorded.
adf-serials.com.au notes that the fatal accident just after take-off from Cairns, QLD occurred on 05/12/45. The Australian War Memorial website notes the accident occurred on 05/03/45, which aligns to when the aircraft was subsequently Struck Off Charge on 13/03/45. The adf-serials.com.au date is a typographic error and I have used the AWM website date. Adf-serial.com.au states that the aircraft crashed on takeoff. However, in The RAAF Hudson Story, Book Two, p.279, David Vincent cites the Court of Inquiry which noted that the aircraft crashed while manoeuvring to land at Cairns, with the cause unknown. It mentioned that the pilot’s lack of instrument flying experience may have contributed.
|
| A16-120 | adf-serials.com.au notes that the aircraft suffered a buckled centre section in a landing accident on 28/04/42 but does not provide the [location].
The aircraft was then sent to 1 Aircraft Depot, RAAF Station Laverton, VIC on 04/05/42 then 5 Aircraft Depot, RAAF Station Forest Hill, NSW on 23/05/42 for repairs. The website notes the aircraft remained there until 1943, yet it has the aircraft at 6Sqn on 22/05/42. I think this is typographic error and it should be 22/05/43.
On 24/08/43 the aircraft was at 7 Aircraft Depot, RAAF Station Tocumwal, NSW for modification to transport role. It was to be issued to 38Sqn but instead proceeded to Port Moresby on 04/09/43 for use by General Blamey then on 18/11/43 for use by Air Vice-Marshal Jones. adf-serials.com.au does not provide advice on which unit(s) operated the aircraft in support of these two senior officers.
On 10/12/46 the aircraft was sold to H. Ellis of Shermans Motors, Dubbo, NSW. The spelling of Skerman’s on adf-serials.com.au is a typographic error.
|
| A16-122 | adf-serials.com.au notes that on 29/04/42 the aircraft struck a drain on landing and the undercarriage collapsed and on 16/11/42 the aircraft was involved in a ground collision with the wingtip of A16-116. Both events occurred whilst assigned to 14Sqn RAAF, RAAF Station Pearce, WA. The records do not state the [location] of each event.
adf-serials.com.au does not note the [date] that the aircraft’s allocation to 38Sqn was cancelled.
|
| A16-124 | adf-serials.com.au notes that on 28/01/42 the aircraft struck a rabbit burrow breaking the tail wheel strut and on 01/06/42 the aircraft carried out a forced landing when the port engine failed. The records do not state the [location] for each event.
adf-serials.com.au notes that aircraft was at 1 Aircraft Depot, RAAF Station Laverton, VIC on 16/09/43 but the event is placed out of date sequence on the website. I have assumed this to be an error in transcribing the record onto the website rather than the date being in error.
adf-serials.com.au notes that on 14/10/43 the aircraft transported Beaufort aircraft parts to 1 Aircraft Depot, RAAF Station Laverton, VIC and the next event is its allocation to 01/11/43 to 1 Special Duties and Performance Flight, 1 Aircraft Depot, RAAF Station Laverton, VIC. There is no record of the [date] the aircraft’s allocation to 38Sqn RAAF was cancelled. adf-serials.com.au does not record the [date] of the aircraft’s subsequent reallocation to 38Sqn RAAF nor a [date] for is later cancellation.
|
| A16-131 | adf-serials.com.au does not record the [date] the aircraft was allocated to 38Sqn RAAF following its allocation to 7 Aircraft Depot, RAAF Station Tocumwal, NSW on 07/09/43 for modification to the transport role.
adf.serials.com.au does not record the [location] of the accident on 12/09/45 when the aircraft ran out of fuel and landed wheels up on a beach. Likewise, adf-serials.com.au does not record the [date] the aircraft was sent to 1 Central Recovery Depot, Werribee, VIC for survey nor the [date] that 4 (Maintenance) Group, Melbourne advised to write-off.
|
| A16-134 | adf-serials.com.au does not record the [date] the aircraft’s allocation to 38Sqn RAAF was cancelled.
|
| A16-147 | adf-serials.com.au notes the aircraft was allocated to 38Sqn RAAF on 24/08/43 then the allocation was cancelled on 12/11/43. There is no indication the aircraft was flown by 38Sqn RAAF or any other unit during this period. The aircraft may have been flown by the Sqn before being modified for the transport role or it may have remained ‘parked’ waiting modification.
The aircraft was subsequently modified for the transport role, arriving at 7 Aircraft Depot, RAAF Station Tocumwal, NSW on 23/11/43.
adf-serials.com.au notes the aircraft was reallocated to 38Sqn RAAF on 08/01/44 but does not record when the [date] the allocation was cancelled. |
| A16-148 | adf-serials.com.au does not record the [date] the aircraft was sent to 1 Aircraft Depot, RAAF Station Laverton, VIC for fitment of Long Range Fuel Tanks nor the [date] the aircraft’s allocation to 38Sqn RAAF was cancelled. |
