Croatia's Ministry of Defense reports the country's navy has received an undisclosed number of autonomous underwater vehicles from the United States.

The Remus 100 vehicles were manufactured this year, the ministry said, and were received as a donation.

"The donated vehicles are of very recent date ... and are intended for various underwater operations, and will greatly upgrade the counter-mine capabilities of the Croatian Navy and by extension the maritime protection capabilities of the Republic of Croatia," it said.

The Remus 100 autonomous underwater vehicle is manufactured by Hydroid Inc., a U.S. subsidiary of Kongsberg.

Croatian Navy personnel who will operated the vehicles have been trained by Hydroid – Kongsberg.
