Design
Doctor Manuel Mantilla is one of five Mantilla-class patrol boats ordered by the Argentine Naval Prefecture in 1981, corresponding to the coast guard cutter “Halcon II” type, designed and build by the Spanish Empresa Nacional Bazán shipyard. The design is optimised for long range open seas patrols, for prolonged periods of time away from port.Mantilla has a steel hull and superstructure, with a single mast atop, behind the bridge. She is powered by two Bazán-MTU 16V-956-TB91 marine diesel engines of 2500kw each, driving two Variable-pitch propellers; with a maximum speed of 18kn. The design has a maximum range of 3650 nautical miles at a cruise speed of 16kn. She has an additional bedroom at the bow to allow her functioning as a training ship.
She has 3 electrical generators of 185Kva each, powering a varied array of systems: controls and communications system that integrates with other PNA air and surface assets; navigation radar; echosound; direction finder; and helicopter navigation control.
Mantilla is equipped with two water cannons for firefighting, anti-contamination gear, active stabilizers and a retractable hangar and landing pad with support facilities for an Alouette-sized helicopter. She is armed with a single 40mm L/70 Bofors dual-purpose autocannon in a position at the front of the bridge.
