This LR2 was built in 1975 by Vickers-Slingsby, a subsidiary of Vickers Oceanics Limited acquired in 1969. The craft weighs approximately 12 tonnes. Mounted to the side of the craft are two large cylindrical battery pods which are detachable so they can be exchanged for fully charged ones from its support ship. The LR2 is manoeuvred by a large main propulsion motor in a fixed position at the back, alongside two smaller directional propulsion motors on either side of the hull. The front of the craft has a single large acrylic window which the crew would use to see where they are going. The conning tower of the LR2 also has an acrylic window to see over the top of the craft. The vehicle’s manipulator arm and claw are also positioned below the front acrylic window. The body of the LR2 is painted white and red, and with the words ‘Vickers Oceanics LR2’ painted on the sides of the submersible. LR2 GRP pressure hull. 1975
