Ship project history: They were the first US submarines with deck guns. Their 76mm/23s retracted vertically into a deckhouse until only about half the barrel was extended, to reduce underwater drag.

    Of the first four boats, three failed on their surface runs; two failed their submerged battery runs. All required extensive overhauls before they could be accepted.

Modernizations: 1918, AL-1-4, 9-11: + SC sonar

Naval service: During 1917-18, L1-4 and L9-11 were stationed at Bantry Bay, Ireland. British waters they wore 'AL' numbers on the conning tower to distinguish them from the British 'L' class.
