Built in Germany in the 1970s by yacht-makers Abeking & Rasmussen, the wooden-hulled vessels are immune to magnetically-triggered mines.

They conduct missions through magnetic, mechanical and acoustic means.

Two shafts are powered by four Maybach diesel engines which produce 4,500 BHP, allowing the vessels to reach speeds of 24 knots.

These wooden-hulled vessels, built in Germany during the 1970s by yacht-makers Abeking & Rasmussen, are uniquely designed to be immune to magnetically-triggered mines.

Their specialized capabilities make them valuable assets for coastal defence and mine-clearing operations.
