An even larger U-cruiser was proposed under "Project 47", but never reached construction; it would have displaced 2,500 tons, had a top speed of 21 knots (39 km/h; 24 mph), and been armed with four 150 mm guns as well as six torpedo tubes, two of which would have fired to the side.

were fitted, but the main armament was the two 15 cm deck guns, which could be laid on target by a rangefinder on the aft section of the bridge. The conning tower's command centre was protected by 90 mm (3.5 in) of armour against the guns typically carried by enemy merchant ships,
395:
The later "Project 46(a)" specified even more powerful U-cruisers, of a similar displacement to the Type 139 boats, but with an increased surface speed of 18 knots (33 km/h; 21 mph), and with two 88 mm deck guns in addition to the two 150 mm guns.

while the pressure hull was thicker than usual at 25 mm (0.98 in), so as to increase diving depth. The superstructure was also raised by 2 m (6 ft 7 in) so that a shell hitting it would not penetrate the pressure hull.

and their intended purpose was to capture or destroy merchant ships on the surface; their large-calibre deck guns and comparatively high speed allowed them to engage even armed merchant vessels.

sank four ships from May 1918, and sank the last ship to fall to a Type 139 U-boat in World War I on 14 October 1918 the NRP Augusto de
Castilho,a portuguese armed mine hunting ship.
