. The ships are designed by an Australian naval architecture firm Sea Transport Solutions, which is based on Queensland's Gold Coast. The deal was canceled due to the extensive delays as the Navy was not satisfied with the timeline and a fresh award for construction of another class of survey vessels to the GRSE has also been undertaken.

Description

The ships are intended to undertake coastal hydrographic survey, required for production of nautical charts and publications aimed at improving navigation through waters closer to coasts. The ships are also capable of limited coastal defence role in an emergency, limited search and rescue and limited ocean research. The ships are equipped with standard hydrographic survey equipment such as advanced electronic positioning system, multi-beam swath sounding systems and sub-bottom profiler. The ships also carry two survey motor boats along with Kongsberg Maritime's ''Hugin 1000'' Autonomous underwater vehicle (AUV) for closer investigations. The catamarans are propelled by four Cummins engines as well as two bow thrusters. The entire propulsion, navigational and power management packages of the vessels are integrated in a L&T supplied single state-of-art integrated platform management system. The ship is also equipped with sophisticated Integrated Bridge System from L&T. The ships have ergonomic accommodation for the six officers and 44 sailors.

Cancellation of the deal

Indian Navy cancelled ₹8000 crore (US$1.1 billion) deal with Alcock Ashdown over 10 year delays in a contract to supply of the six vessels. According to Navy officials only one of the vessels has been delivered and there is no sign or any timeline for the other 5 ships. Further, the Ministry of Defence has awarded another contract for the construction of four Survey Vessels for

(GRSE) Limited, Kolkata after it became the L1 bidder in the competitive bidding. These ships have a displacement of 3,300 tonnes. Therefore, these ships are likely to be more advanced and outperform the Makar Class which has a displacement of only 500 tonnes. So, this further reduces the chances of the completion of the deal and hence the Makar class will consist of only 1 ship.
