Project history

Fast shallow-draught armoured motor gunboats, projected and built by Hanz Danubius at Budapest. They were armed by 40mm/45 tank guns in turrets. In each of turrets also two 8mm MGs were placed, two more MGs were installed on movable mounts in aft part of deck house and could fire through one of three loophopes. The armoured citadel defended deck house, magazines and machinery. Complexity of manoeuvring on high speed (when the bow too strongly went out water, covering the view from low deck house) appeared the basic lack of the project.  Building of 5 more boats was begun in 1942-1943, by late 1944 they remained incomplete, and already launched hulls were scuttled. Only in 1949 salvaged PM3 was commissioned as PN11 in significantly altered kind and Soviet armament. Two more boats were salvaged in the late forties and completed in 1956 under the changed project as PN31 and PN32. All three were written off in 1973.
