Pittwater's Torpedo Wharf and Range
As seen in Naval Visits to Pittwater 1788-1952 the testing of torpedoes in Pittwater has numerous instances prior to the establishment of the torpedo wharf at Taylor's Point.
TORPEDO PRACTICE AT PITTWATER.
Shipmasters and others are hereby notified that Torpedo Practice will take place In Pittwater, commencing on 10th October, and continuing dally (Saturdays and Sundays excepted) until 27th October, 1933. Practice will only take place between the hours of 8 a.m. and 12 noon, and between 1 p.m. and 4p.m. Torpedoes will be fired from a destroyer anchored towards the southern end of Pittwater, near Taylor's Point, in a northerly direction of Observatory Point. Mark buoys will be laid at the northern end of torpedo range. A red flag will be flown by the destroyer while practice is in progress, and a red flag will be flown by a motor launch in the vicinity of Rock Head, when range is dangerous. Vessels are not to proceed south of Observation Head or north of destroyer when these signals are flying.
The signal (Black Ball over the International Code signal K.J.Y.), will be flown with small size flags from a boat fitted with a mast anchored in the fairway, about 440 yards to the north of the torpedo range limit.

On the 26th of March 1941 the trawler Millimumul was sunk east of Broken Bay after hitting a mine laid by Pinquin, a German auxiliary cruiser. As May became June in 1942 torpedos from Japanese miniature subs were fired at Bondi, Bellevue Hill and into Sydney Harbour, sinking HMS Kuttabl and killing some of the young men billeted onto this vessel. As early as 1940 Australia began to lose ships to mines laid by German vessels off our Victorian coast and ships further at sea to torpedo attacks. Protection against further attacks and preparations against invasion were crucial. The manufacture of torpedos within Australia, decentralising this weaponry production from Britain, came as a request from Admiralty.
TORPEDOES AND MINES
THE decision to manufacture torpedoes in Australia, taken at a meeting of the War Cabinet on 22nd December 1941, committed the country 's precision engineering to a most difficult undertaking; by reason of the position occupied by torpedoes among modern armaments, the undertaking was one of great potential importance . With sea power as the corner-stone of Britain's dominant strength among world powers in the nineteenth century it is not surprising that the development of the torpedo was essentially a British achievement, though it was not in the first instance a British invention). Britain's early lead in the adoption of the torpedo owed much to the enthusiasm of Commander (later Admiral Lord) Fisher, but other great powers were not long in entering the field. The tremendous possibilities of the weapon were first apparent during the war of 1914-18 when Germany, by means of the U-boat and the torpedo, inflicted such heavy losses on merchant shipping that she very nearly brought Great Britain to her knees. During the two decades that followed the first world war the torpedo acquired even greater destructive potentialities by the development of methods for dropping it from aircraft, and no great insight was required to predict the part the torpedo would play in a future war.
The manufacture of torpedoes in Britain was carried out principally by a private firm, the Whitehead Torpedo Company, which manufactured for all corners, and by the Admiralty at Greenock, Scotland . In July 1941 the Admiralty, concerned at the possibility that Britain 's production of torpedoes might be hindered if not prevented altogether by bombing or invasion, began to investigate means of providing alternative centres for such an emergency. Manufacture in Britain had been decentralised as far as practicable but nothing had been done towards establishing centres outside Britain.
The final and most important of all the tests applied to a torpedo was ranging, which consisted of firing it from a discharge tube located on shore over a carefully selected stretch of water. During ranging the war head was replaced by a dummy head filled with water. At the end of the run the water was expelled and replaced by air, which caused the torpedo to float upright and so made it easy to recover. The direction, depth and speed were closely observed and noted with special instruments.

A range surveyed by the Hydrographic Branch of the R .A.N. was set up at Pittwater, in Broken Bay, 30 miles north of Sydney. Firing tubes, observation station, workshop, pier and target rafts were designed and erected while the torpedoes were being made. Normally every torpedo was ranged twice. The ranging of the first Australian-made torpedo at Pittwater on 24th February 1944 was a signal success ; it sailed straight through all Admiralty tests without needing any of the small adjustments that are often called for in a first trial. The range officer, Lieutenant Owens, reported, "the performance of this torpedo could not be bettered" .

In December 1942 construction of this range was not without difficulty as reported on reflection after the war;
The torpedo range at Pittwater was another difficult survey job. - Concrete blocks had to be dropped from a naval tender at a specific point so that the targets could be anchored. It was a difficult task to manoeuvre the vessel into the correct position. Mr. Brett said this was the first survey work ever carried out in Australia by wireless.."

By late 1943 the first Australian made torpedoes were being tested at Pittwater.
Torpedos in their original forms were what we today would call ‘mines’. From around 1900 the term 'torpedo' has been used to designate an underwater self-propelled weapon. The first working prototype of the modern self-propelled torpedo was created by a commission placed by Giovanni Luppis(Croatian: Ivan Lupis), an Austrian naval officer from Fiume (now called Rijeka), a port city of the Austro-Hungarian Monarchy (modern Croatia), and Robert Whitehead, an English engineer who was the manager of a town factory. In 1864, Luppis presented Whitehead with the plans of the salvacoste(coastsaver), a floating weapon driven by ropes from the land, and made a contract with him in order to perfect the invention. (1.)

The R.A.N. was given responsibility for setting up a Torpedo Factory and supervising manufacture:
The site chosen for the factory was that of the North Sydney Gasworks, and as a result of quick and effective action by the Business Board immediate possession was gained late in 1941. The original plan was to economise by adapting the existing buildings, which were in some respects suitable, but when after several months work had not even begun, the navy sought the aid of Mr Essington Lewis. Lewis decided that to keep pace with the program agreed upon it was necessary to demolish the existing building and erect an entirely new factory. The next day, a Friday, he called a meeting at his office in Melbourne which was attended by all concerned, including representatives of the architects and the contractor from Sydney. A contract was placed that night and the contractor began to clear the site on the following Monday morning. This was a good example of what could be done when it was possible to make a clean cut through red tape. By February 1943 the buildings, known as the Royal Australian Naval Torpedo Factory, were completed, in remarkably short time. The factory was well designed and splendidly equipped; so completely did its structure harmonise with its surroundings that despite the fact that it covered over 100,000 square feet, it was by no means a conspicuous landmark.

Supervision of all Pittwater torpedo activities was also supervised by our R.A.N.:
Commonwealth Navy Order 287 (1947)
R.A.N. TORPEDO RANGE, PITTWATER, N.S.W.
The R.A.N. Torpedo Range is situated in Broken Bay, N.S.W., the firing point being on Taylor's Point, Pittwater, and the range extending from there in a northerly direction.
2. Transport of torpedoes is normally carried out by road from the R.A.N. Torpedo Factory, a distance of 22 miles, as no vessel with a draught greater than 12 ft. 6 in. can enter Pittwater. 3. The following firing guns are fitted:—
1—No. 21-in. above water firing tube.
2—No. 18-in. tubes.
1—No. 21-in. submerged firing tube.
There is also a launching cradle for use in running torpedoes not otherwise catered for.

4. The Torpedo Range workshop is capable of carrying out complete overhauls on all torpedoes.
5. Applications for torpedoes to be ranged should be made by signal to Admiral Superintendent, Sydney, repeated for information to Superintendent, R.A.N. Torpedo Factory.
6. Transport of torpedoes from the ship's side to the range and return will be arranged by the Superintendent, R.A.N. Torpedo Factory.
The Torpedo wharf soon became part of the local landscape, a landmark:

Recovering these devices for a second firing and to examine their devices was part of naval duties. The torpedo range had several firsts in testing these devices, among them:
Australia Makes First Torpedo SYDNEY, Wed. (AUP). The first Australian built torpedo for use by surface ships was successfully tested at Pittwater torpedo range today. Destroyers and frigates will be the first RAN ships to be equipped with the new 21in. torpedoes. Navy Minister McMahon, who watched the tests today said Australian built torpedoes were part of Australia's contribution to world peace.

Pittwater after World War II had become a more residential area with young families as much as retirees finding such a beautiful place so close to a city center, and afforable then, more and more attractive.
As with the Propsector Powder Hulk and an Australia no longer under threat of conflict arriving on her shores, those who dwelled on the shores of the estuary began to question why vital training could not be carried out elsewhere. A few torpedoes going astray, the basis for 'ranging', further underlined a need for the R.A.N. to test elsewhere and use the torpedo wharf and building for another training necessity;
R.A.N. Torpedo Crashes Into Small Island
Sydney, Wednesday – A Royal Australian Navy torpedo ran off course and crashed on to rocks on private property on Scotland Island, Pittwater, to-day. It was the second navy torpedo to "run- away" since August 26th when a torpedo ran on to Clarevile Beach, Avalon, through scores of swimmers narrowly missing pleasure craft moored nearby. A navy spokesman said today the latest torpedo was fired in routine tests over the navy range in Pittwater, and had not been , loaded. No-one had been injured and no damage had been caused. However, a local resident said the torpedo crashed through a private swimming pool and sea wall on privateproperty. The Minister for the Navy, Senator Gorton, last August said the testing range would not be moved. He had called for a report on the previous torpedo, but said there was little risk in the present siting of the range. R.A.N. Torpedo Crashes Into Small Island. (1960, January 28).

Some items from Warringah Shire Council minutes charting the establishment and continuance of the RAN Torpedo facility at Taylor's Reserve:
Taylor’s Point Reserve Proposal to Occupy, for the purposes of the Torpedo Station, an additional area of the reserve immediately adjacent to the Station on its western side and in front of the swimming baths: A further letter, dated 8th anat. from the State War Effort Co-ordination Committee, together with the accompanying copy of, a letter received by that Comnittee from the Department of the Interior further in regard to this Taylor matter was read, and 'explanatory plan received with such letter was displayed. After discussion it was resolved, That the State War Effort Co-ordination Committee be informed that if the Authorities concerned will agree to remove the public baths to a position on the eastern side of the building, as suggested at the conference, the Council will raise no objection to the occupation by the Commonwealth for the duration of the war of the additional area on the western side of the building as shown on' the plan. (Crs. Batho, Langdale) Further in regard to the matter the President pointed out that the torpedo practice operations could extend from Taylor's point Reserve northwards nearly to Lion Island, and would interfere with the use of that portion of Pittwater by the public on occasions. On his motion, seconded by Cr. Batho, it was resolved; - That a letter be sent to the Department of the Navy for an assurance that the mooring of punts in Pittwater will not be a permanent thing after the war's end that a copy of such letter be sent to Mr. Spender, the Federal Parliamentary member for the district.

Submittor (06) Royal Australian Navy (HMAS Penguin) Issue The Navy has provided details on the proposed relocation of a number of boat moorings at Taylors Point. Approximately 80 buoys located in Naval waters off Taylors Point are restricting access to both Naval and public wharfs. The commanding officer of HMAS Penguin, who is responsible for the administration of that part of Pittwater controlled by the RAN has requested the MSB to relocate about 15 buoys. The RAN has never given authorisation for moorings to be located in waters which it controls. The proposed relocation has been made necessary by the requirement to ensure safe and reasonable access to the wharves at Taylors Point. A sketch showing the moorings in question was attached to this submission. The RAN proposes to contact the owners of the moorings before relocation occurs. Comment The Navy's comments have been noted. Further consultation should occur with MSB Waterways Authority regarding a number of moorings to be allocated in the Clareville - Taylors Point area. Further review of the recommended maximum number of moorings in Area 5 or the configuration of this area as indicated in Map 2 and Table 2 in Section 6.3 of the draft DCP/Policy may be required. This matter will be discussed at the next meeting of the Pittwater Planning Advisory Committee.
