Bluefin 21 – a robotic submarine was launched on 14 April 2014 to solve the mystery of the lost Malaysian plane MH370. The decision of sending a Bluefin-21 was taken when the search team felt that the batteries of Black Box had expired making them incapable of sending signals.
This autonomous unmanned under water vehicle was launched from the Australian navy ship Ocean shield and would go under Indian Ocean.
This submarine can create three-dimensional sonar map of any debris on the seafloor by using its side-scan sonar.
Bluefin-21
- It is autonomous, underwater, highly modular vehicle.
- It can carry payloads and multiple sensors simultaneously.
- Its high energy capacity makes it capable of carrying extended operations even at the greatest depths.
- It can operate from various ships of opportunity worldwide.
- Ease in transportability is another cause behind its application in time-critical and remote operations.
- The vehicle design consists of battery modules, swappable payload sections for in-field mission reconfiguration. Its small size and capability to be launched and recovered from a simple A-frame or docking head allow it to take advantage of ships of opportunity. Use of INS provides the best possible navigation accuracy to Bluefin-21.
