Editing Battleship (section)

=== Cost-effectiveness ===
Battleships were the largest and most complex, and hence the most expensive warships of their time; as a result, the value of investment in battleships has always been contested. As the French politician [[Etienne Lamy]] wrote in 1879, "The construction of battleships is so costly, their effectiveness so uncertain and of such short duration, that the enterprise of creating an armored fleet seems to leave fruitless the perseverance of a people".{{sfn|Dahl|2005|p=115}} The ''Jeune École'' school of thought of the 1870s and 1880s sought alternatives to the crippling expense and debatable utility of a conventional battlefleet. It proposed what would nowadays be termed a [[sea denial]] strategy, based on fast, long-ranged cruisers for commerce raiding and torpedo boat flotillas to attack enemy ships attempting to blockade French ports. The ideas of the ''Jeune École'' were ahead of their time; it was not until the 20th century that efficient mines, torpedoes, submarines, and aircraft were available that allowed similar ideas to be effectively implemented.{{sfn|Dahl|2005|pp=122–124}} The determination of powers such as Germany to build battlefleets with which to confront much stronger rivals has been criticized by historians, who emphasize the futility of investment in a battlefleet that has no chance of matching its opponent in an actual battle.{{sfn|Sondhaus|2001|p=225}}
