The arrangement of gondolas and the fitting of engines in all
ways corresponds to the original arrangement of R 23, with the
exception that they were suspended closer to the hull owing to
the absence of the external keel. The substitution of the wing
car of the 33 class for the original after gondola, carried out
in the modifications undergone by the ships of the 23 class, was
not adopted in these ships, as the wireless compartment installed
in the keel in the former was fitted in the after gondola in the
latter.

The disposable lift of these ships under standard conditions is 7
1/2 tons, which shows considerable improvement on the ships of
the former classes.

Summarizing as before, the performances appear as under--

Speed:
Full 56 1/2 miles per hour
Normal 53 " " "
Cruising 45 " " "

Endurance:
Normal 19 hours = 1,015 miles
Cruising 23 1/2 " = 1,050 "


The two ships of this class, which were commissioned, must be
regarded within certain limits as most satisfactory, and are the
most successful of those that appeared and were employed during
the war. Escort of convoys and extended anti-submarine patrols
