PRESSURE HULL: Central cylinder with an OD of 1.60 m capped with a forward cone closed by a hemispherical cap and after cone through which 



shafting penetrates. Hull is composed of 210-mm-thick steel. 



BALLAST/BUOYANCY: Four main ballast tanks of 2.4-m^ capacity blown by compressed air. Gross pre-dive ballasting is adjusted by the removal 



or addition of lead weights on the keel. Submerged buoyancy is adjusted by fore and aft variable ballast tanks within the hull which allow a total 



adjustment of 1 30 kg. An anchoring device consisting of 20 m of cable and a 200-kg anchor allows vertical hovering control near-bottom. 



PROPULSION/CONTROL: One.three-bladed propeller at the stern (5-hp) provides main propulsion. Two vertical thrusters and one lateral thruster 



all of 0.5 hp. 



TRIM: Up/down bow angles can be obtained by transferring fresh water between two forward and two aft tanks within the pressure hull. 



POWER SOURCE: Nickel-cadmium batteries are located in jettisonable pods outside the hull. The batteries are pressure compensated and provide 



all electrical power. A 28-V battery within the hull is for emergency power, 



LIFE SUPPORT: Gaseous O2. CO2 is removed by soda lime. Monitors for O2, CO2 and cabin pressure. Three individual emergency breathing 



apparatuses are connected to the main O2 supply. 



VIEWING: Five viewports. One is in the access trunk and four are on the pressure hull bow. 



OPERATING/SCIENTIFIC EQUIPMENT: UQC (Straza ATM 504 A) which also operates as a transponder interrogator, an echo sounder, a pinger 



and a transponder. Depth gage, TV, VHF radio, gyrocompass, two recording echo sounders, sample basket. 



MANIPULATORS: One, with a reach of 1.60 m. 



SAFETY FEATURES: Battery pods and manipulator are jettisonable (total about 900 kg). Anchor cable can be cut with a pyrotechnic device. Two 

 fire extinguishers. 



SURFACE SUPPORT: Supported by the ship TRITON which may either tow it to the dive site or launch/retrieve it on station. 

 OWNER: Operated by the Groupe d'Etudes et de Rescherches Sous-marines (GERS) and the French Navy. 

 BUILDER: French Naval and Construction yard, Brest. 

 REMARKS: Undergoing sea trials as of February 1974.
