Low-Maintenance Submarines
The Daphne-class vessels were manufactured and noted to be low-maintenance while being highly mobile and carrying a limited amount of crew members. This was what made it so appealing to less developed countries with substantially more modest military budgets. This made France a lot of money, as the nation became a highly popular source for military expenditure for countries across the world. Minerve and her twin propellers were operated by an electric motor and two diesel engines.
Features of the Minerve
Minerve measured an estimated 190 feet from bow to stern and an average 22 feet across the beam. She had a range of 5,200 miles and an estimated 883 tons. The sub could manage to amass an 18 mph speed underwater and 15.5 mph above waves. There were eight torpedo tubes on the front of the sub while another four around the back. Despite its affordability, this class of submarine was still highly capable, with the capacity for espionage and battle.
