Armaments of Home Ports issued a report in which they recommended the removal of all Brennan torpedoes from fixed defences due to their comparatively short range and the difficulty of launching them at night. Manufacture of the Brennan torpedo finished in 1906. Installations In 1891 It was intended to build 15 stations as indicated in a report to the Director of Artillery. We have now completed or in progress 7 installations viz. Thames (Cliffe), Medway (Garrison Pt), Portsmouth (Cliff End/Fort Albert), Plymouth (Pier Cellars/Cawsand Bay), Cork Harbour (Fort Camden), Malta (Tigné and Ricasoli). Further sites proposed as funds become available at Plymouth (Bovisand), Milford Haven, Clyde, Forth, Falmouth, Hong Kong, Singapore and St Lucia. The first seven were completed but out of the other eight only the one at Hong Kong was completed. The plans for two installations at Dale Point and Great Castle Head, Milford Haven were drawn up but not carried out. Four Brennan installations were added to existing fortifications at Fort Albert on the Isle of Wight, Cliffe Fort on the Thames, Garrison Point at the entrance to The Medway and at Fort Ricasoli at the entrance to the Grand Harbour at Malta. With the exception of Ricasoli, the design of these was constrained by the existing structure and resulted in unique designs. In addition the ones at Fort Camden at Cork and Tigné at Malta together with proposed designs for Milford Haven followed a very similar layout while the Installations at Lei Yue Mun in Hong Kong and Pier Cellars at Plymouth were individual designs. Installation remains The installation at Fort Albert has been completely destroyed. That at Cliffe Fort partially exists, including a slipway and parts of a telescopic control tower. Parts of the installation at Garrison Point survive including the direction stations on the face of the fort and parts of the slipway supports. The complete installation at Pier Cellars still exists although it was greatly modified during later use for midget submarines. At Malta the Tigne installation was later converted for use as the boom defence station but the rooms still exist. At Fort Ricasoli the complex of buildings still exist and the slipway is mostly intact. At Lei Yue Mun the installation has been incorporated into a museum with a replica Brennan Torpedo on display. At Fort Camden most of the installation still exists but is derelict. Surviving examples The only remaining
