The Indonesian government is set to give the green light to the development of the Tank Boat concept after the project was given the official name Antasena by vice president Jusuf Kalla and minister of defence Ryamizard Ryacudu on the first day of Indo Defence 2016.
Being developed by PT Pindad, PT Lundin and CMI Defence, the Tank Boat concept was first displayed in 2011, but has been developed over the past two years under a design feasibility study. This has confirmed the structural design and hydrodynamic characteristics of the novel 18m composite catamaran platform, and the integration of the 105mm main armament.
The design has now been frozen, and the full-scale Tank Boat model on display at Indo Defence will in fact serve as the mould for the prototype. Final negotiations are under way to build the first of class, with current plans aiming at delivery by the end of 2017.
The Tank Boat concept has been conceived to provide planned ‘swamp’ battalions with an improved amphibious/riverine manoeuvre and fire support capability.
The main armament will be a CMI Defence remote-controlled turret armed with a stabilised 105mm gun able to fire various natures of fixed 105mm ammunition including high-explosive via a bustle-mounted automatic loader. The mock-up of the turret shown here is also fitted with a Bofors Lemur remote weapon station armed with a low recoil Orbital ATK 30mm cannon.
