During the 1950’s, the growing threat from Submarines, led the Royal Australian Navy to consider a quick reaction, long range ASW torpedo delivery system as an alternative to the USN’s ASROC and the RN’s Match. Full scale research and development began in 1960 using the Turana target drone as the basis for the delivery platform. Shipboard tests began in 1963 and the Government Aircraft Factory (GAF) began production of three variants M3, M4 and M5 in 1965. The M4 variant had a guidance system designed to interface to a full tactical data handling system while the M3 and M5 variants used a simpler system with a dedicated fire control system. The IKARA is an unmanned miniature aircraft with clip on upper and lower stabilizers and wings. The upper stabilizer (SVU) housed and electronic package that transmitted flight data back to the launch platform and received updated target acquisition data during flight. Flight maneuverability was provided by elevons fitted into the trailing edge of each wing, these were operated by an actuator system that received flight correction data transmitted to the autopilot from the fire control system. The payload, either the Mk44 or Mk46 lightweight torpedo was suspended to the underside of the airframe and faired into the body to provide and aerodynamic shape. The forward section of the body housed the autopilot and the thermal battery unit. Propulsion was provided by the MURAWA steel cased, solid propellant rocket motor with a combined boost and sustainer stage. IKARA was capable of engaging a target to the maximum range of the ships sonar, regardless of weather conditions. Target information is fed into the fire control system, which calculated to drop zone for the torpedo taking into account speed and direction of launch platform and target, win speed etc, then tracking the missile to the drop zone where command signals initiate torpedo release.

This is a set of six staff photographs of the Army Survey Regiment’s Officers, Warrant Officers and Sergeants, and each of its four Squadrons at Fortuna, Bendigo in December 1982. Note - Air Survey Squadron’s photo was probably taken in July 1982 as they appear in winter dress. Air Survey Squadron was responsible for aerotriangulation, photogrammetric feature extraction and the AUTOMAP 1 system. Typical tasks were flight planning the acquisition of aerial photography, pugging, mensuration and block adjustments, photogrammetric extraction of topographic features from aerial photography, digital feature editing, map compilation, operating the scanner/plotter, operating the AUTOMAP 1 system and computer programming by civilians. Cartographic Squadron was responsible for the production of the following military products: Joint Operation Graphics, small-scale RAAF Air Charts, large-scale topographic line maps and orthophotomaps. Cartographic technician tasks were scribing, compiling, retouching, masking, type setting, type stickup, terrain embossing, correcting and proving quality control. Headquarters Squadron was responsible for the planning and coordination of map production and contracts. It also performed administrative and support functions such as personnel administration, pay, finance, transportation, records, map Library, kitchens, messes and facility maintenance. It was staffed by Army personnel from RASvy, RACT, AACC, RAAOC and RAEME corps. Other supporting staff at this time included the RAAF Liaison Officer, RAN Liaison Officer and several civilians employed in administration, the Q-Store and grounds maintenance. A component of the Army Svy Regt’s cartographic map production was carried out by the Detachment, a sub-unit located at Bonegilla next to the School of Military Survey. Lithographic Squadron was responsible for the reproduction of map materials and printing of military map products. The main tasks undertaken by photographic technicians were photographic enlargements, reductions and duplication of map reproduction material and processing of aerial photography. Printing technician tasks included platemaking, offset printing, map stock despatching and proofing.This is a set of six staff photographs of the Army Survey Regiment’s Officers, Warrant Officers and Sergeants, and its four Squadrons, at Fortuna, Bendigo, 1982. The black and white photographs were printed on photographic paper and are part of the Army Survey Regiment’s Collection. The photograph was scanned at 300 dpi. No personnel are identified.
