In the eighties, the Royal Netherlands Navy acquired 15 minehunters of the Alkmaar-class. They were deployed worldwide in conflicts (the Red Sea, the Persian Gulf and the Libyan Sea). In all European waters they exercised and cleared historical ordnance. HNLMS Haarlem represents the rich history of the tripartite minehunters of the Royal Netherlands Navy. This book presents an overview of the development and operational use of the ‘Tripartite Class Minehunter Haarlem’ warships with many photos and illustrations. Bob Roetering worked as a senior officer and Commander of the Mines Service at the Royal Netherlands Navy. He served on hunters and frigates.
