Aircraft /Boat Crane ircraft/Boat Crane:

AMPHION/PERTH's crane was a 7 ton lifting crane manufactured by Joseph Booth & Bros. based at the Union Crane Works, Rodley, Leeds UK. ( Ref: NMM UK Ships Plans files)

The crane was replaced by a different one during the Sept-Oct 1941 refit. (The original crane continued in use as a lifting crane at Cockatoo Dockyard Sydney and later at the Balmain Power Station until 1990. It is currently being restored.

Aircraft Catapults:
(As HMS Amphion no catapult was fitted)
The catapults fitted to PERTH were made by MacTaggart-Scott of Scotland.

The 1st Catapult.
According to the book ‘Fleet Air Arm Aircraft, Units and Ships 1920-1939’ by Ray Sturtivant and Dick Cronin, the first catapult fitted to HMAS PERTH was an EIVH. ( E=Extending: H=Heavy). Weight: 19 Tons.

However they state that this catapult was fitted in July 1939 but PERTH never received her first catapult until the latter part of 1940 after she had arrived in Australia.
This catapult was landed upon PERTH's arrival at Alexandria in Dec 1940.
PERTH re-embarked a catapult at Alexandria on 19 July 1941 prior to returning to Australia.

Cronin and Sturtivant say that PERTH received a catapult from AJAX in Aug 1941 which was a model EIIIH. It is quite possible that this was the one offloaded by AJAX a few months earlier and transferred to PERTH on the 19th July at Alexandria just before her return to Australia. (No files appear to exist in the Nat.Archive).

The 2nd Catapult
A newer (53ft?) catapult replaced it in Nov 1941. According to a file in the Nat.Arch. of Aust, this was a model E11A(9). The file contains testing reports from 13 Nov 1941 to 15 Jan 1942. (Ref. NAA fileMP138/1, 603/269/187)

The new catapult was first tested with an aircraft on 22 Nov.1941 (Ship's Log)
