Development

Technology Demonstration Vessel was contracted to the Cochin Shipyard Limited by the DRDO in August 2015.[1] This vessel has a length of 118.4 metre, 20 metre width and 7.1 metre draft and having a steel weight of approximately 3900 Tonne.[3]

The original contract for construction of the vessel was signed with Bharati Shipyard, but time overruns forced by the yard's poor finances led to termination of the contract. Subsequently, the Cochin Shipyard won the bid to execute this project.

Steel plate cutting of the vessel was started on 10 August 2016. Dr S Christopher, Chairman, DRDO and Secretary, Department of Defence R&D, launched the mega block assembly of hull blocks of the ship (Ship No.20) on 27 January 2016 at CSL.[3]

The ceremonial event of commencement of Mega Block Assembly of hull blocks of Ship No.20, the Technology Demonstration Vessel, being built for the Defence Research & Development Organisation (DRDO), Government of India was held on 27 Jan 2017 at CSL.
