Surcouf's cruiser-submarine concept is criticised as an attractive paper solution whose practical value fails to justify the compromise. The comparison is a 10-inch gun, judged to offer roughly the rate of fire of a 12-inch or even a 14-inch weapon without enough cost saving to justify choosing it. If cost is the priority, a 9.2-inch weapon is presented as a faster-firing alternative with better value. The criticism concerns whether an intermediate design earns its place through useful performance. It leaves the rest of France's large submarine force as capable offensive and defensive assets, particularly in the Mediterranean.
