An area of 1100 acres was requisitioned under National Security Regulations in October 1942 for a US Army Ordnance Depot, managed by the US Army Services of Supply (U.S.A.S.O.S.). The depot was used for the storage of chemical weapons (persistent gas-filled artillery projectiles). The explosives area was on the eastern side of Bringelly Road (now The Northern Road), and the camp area on the western side.
The depot was evacuated by the US Army on 28 May 1945. This is the date for administrative purposes; actual evacuation had probably occurred progressively over the preceding months.
It seems likely that the US Army hirings were either immediately transferred to the Navy and RAAF or new requisitions covering the same parcels of land were issued. There are indications that, in Navy's case, this was primarily to accommodate ammunition for the British Pacific Fleet, and was initially regarded as a temporary arrangement.
Kingswood camp buildings on the western side of Bringelly Road were disposed of by auction on the site on 30 October 1946 (except for the garage and police office).
By September 1947, the depot had been emptied, but then refilled with Group VII (mass-detonating, e.g. depth charges) stores from Newington. (RANAD Sydney Newsletter, May 1948).
As at August 1948, Defence were in possession of the following lands under the National Security Regulations:
On 17 September 1948 the Admiral Superintendent Sydney wrote to the Secretary, Naval Board recommending, in respect of the camp area:
... that the whole of the area in question be now dehired, and that the quarters of the police guard and the petrol bowser which are now located on this area be moved across the road to a site to be determined in the vicinity of the Depot Office in the main depot area. The other remaining building, (garage shed) to be disposed of to Mr. Fowler or as otherwise may be thought fit.
This recommendation would result in one compact area, in lieu of two areas separated by Bringelly Road ...
On 13 December 1948 the Secretary, Naval Board wrote to the Secretary, Department of Air, intimating that Navy wished to take over the RAAF hirings when they were relinquished.
On 20 June 1949 the Secretary, Naval Board wrote to the Secretary, Department of Air proposing to utilise a cottage on the RAAF section as a residence for the Officer-in-charge of the "Naval Section of the Armament Depot".
Changes were afoot to the existing storage safety distances:
"Far-reaching changes appear in the new tables of Safety Distances issued last year by the United Kingdom Committee, following the large scale test explosions conducted in Germany and elsewhere since the war ended. We are now examining our own storages and tonnages to see what the effect would be if the new distances were applied to existing explosives area, and the results to date clearly indicate that we need more room." (Naval Ordnance Branch Newsletter, May 1949)
On 23 May 1950, Secretary, Dept of Air wrote to Secretary, Department of Navy (171/93/1999) pointing out that both Departments had been paying compensation for the incorrect portions of the depot at Kingswood. This letter says "The area coloured yellow was taken over in 1945, by arrangement with your Department, for the storage of R.A.A.F. explosives." (this yellow area was J.G. McLaughlin's 441 acres 2 roods.)
As at 30 June 1950, the depot was storing Depth Charges Mk 7, Bombs 500lb MC Mk 7, Warheads torpedo 21-inch, Squid projectiles and Shell HE SAP 3-inch aircraft rocket. A total of 50 explosives storehouses were in use, although some were empty due to the poor state of road access to them; storehouses were either fibro igloos, Sidney Williams sheds or Masonite prefabricated huts. The storehouses were untraversed.
Admiral Superintendent minute to Flag Officer in Charge, NSW, dated 16 November 1950, confirms that the police quarters had still not been moved across Bringelly Road, due to uncertainty about the future of the depot.
In connection with a request by Dept of Supply for release of Navy magazines at St Marys, Superintending Armament Supply Officer wrote on 23 April 1951 (Superintending Armament Supply Officer to Admiral Superintendent, 1779) that whilst there was 46,000 square feet of storage at Navy's depot at Kingswood, 25,600 square feet of this was in fibro igloos which, because of their small size, shape and low height, had a much smaller capacity than indicated by the floor area.
At some time in 1951 the Secretary, Naval Board, wrote to the Flag Officer-in-charge NSW (3163/114/1) saying "The Naval Board recognises the necessity for reducing stocks at Newington to ready-use requirements, say five thousand tons, and have asked the Department of the Interior to find a site for a new Armament Depot to accommodate main ammunition holdings in the Sydney area." This was later defined as a depot with a capacity of 14,000 tons
Roads and cleanways were laid to the laboratories.
Secretary Naval Board letter to the Captain Superintendent, Sydney (3163/14/36 of 14 January 1952) refers to works being undertaken including provision of traverses for all storehouses at Kingswood. It also affirms that it is policy to develop a new armament depot in New South Wales to permit the reduction of stocks at RANAD Newington and "a requirement to clear Kingswood as soon as possible."
On 5 March 1953 the Secretary, Dept of Navy wrote to the Director of Works, Dept of Works NSW requesting a contour survey of lands "Following a decision to establish a combined R.A.N. - R.A.A.F Explosives Depot at Kingswood ..."
Secretary, Dept of Navy letter to Director General, Dept of Works (3163/14/95 of 12 June 1953) advises of Navy's in principle decision to establish a Naval Armament Depot at Kingswood and itemises in some detail the facilities required. Included is a rail spur line from the main Western railway line, with sidings within the depot. THis line was never constructed, although preliminary route planning was conducted.
Secretary, Dept of Air writes to Director General, Dept of Works (171/89/203 of 25 March 1954) concurring (with minor exceptions) with layout plans NA 9504 and NA 9549 for the explosives and camp areas of the joint RAN/RAAF armament depot and stating that Navy concurs.
Secretary, Dept of Navy letter to Director General, Dept of Works (5073/14/5 dated approximately 12 September 1955) advises that financial restrictions require that initial construction be limited to 2 explosives storehouses for Category Z explosives. Requisition DNW 236/55-56 for £42,600 issued.
On 10 January 1956, during repair of broken filling in a Depth Charge Mk7 by application of heated Composition RD1061, smoke and flame issued momentarily from the filling hole. Consequently, the Naval Board directed that the "improvised huts used as laboratories" were only to be used for visual examination, gauging and venting pending construction of a permanent laboratory. The lack of supervision was also an issue. Subsequently the Superintending Armament Supply Officer sought the establishment of a position of Deputy Armament Supply Officer to provide continuous supervision of the Kingswood depot. This was refused by the Flag Officer in Charge, who commented: "not more supervision, but better supervision in future."
Contract let on 22 October 1957 to A.W. Edwards Pty Ltd of Glebe for the construction of 4 Explosives Storehouses for Category Z explosives. Requisition DNW 151/57-58 refers.
1958Contract let to W. McNamara Pty Ltd of Riverstone for construction of 1 Painting Room and 4 Laboratory Examination Rooms. Requisition DNW 321/57-58 refers.
Superintending Armament Supply Officer reports on 6 November 1959 that the 4 Storehouses (DNW 151/57-58) are complete except for electrical connection, and that the Laboratory buildings (DNW 321/57-58) will be completed by the end of the month.

Tartar Facility handed over by Dept of Works during quarter ending 31 March 1967.

The Castle Committee's deliberations seem to have been remarkably protracted; their initial recommendation in July 1968 was essentially "business as usual". However, reading between the lines, Navy Office politics resulted in a major reworking of the Committee's recommendations, which by October 1968 included (Navy Office letter 2-204-68 of 15 October 1968):
In the event, some of these recommendations were deferred. Navy Office letter of 21 November 1968 advised FOICEAA that:
