USS L-9 SS 49 which seems to be running her diesel.
You can see the smoke from her exhaust around her stern.
The US "L" class boats had the "A" added to their identifiers so as not to be confused with the British "L" class submarines that were operating at the same time.

USS L-2
USS L-2 SS 41
In July of 1918 while patrolling in the Irish Sea a large explosion rocked
the L-2 about 25 feet on her beam. A periscope was sighted and the
L-2 submerged and tried to ram the submarine but couldn't track the
U-boat well under water, plus the U-boat had superior under water speed.
Later it was suspected that a U-boat had fired on the L-2 but another U-boat,
the U-65, was in the way and was badly damaged and sank. Some time
later when the L-2 was dry docked her hull plating was noted to be heavily
dented from the close by explosion. The U-65 never returned to her port.

USS L-4 SS 43
USS L-4 SS 43
The L-4 spotted a German U-boat on the surface charging batteries and lying motionless. The Capt., LCdr Lewis Hancock, jr., fired a torpedo at the submarine. The Germans saw the torpedo and quickly sped forward and dove evading the torpedo. The L-4 later had almost the same situation and the same result the torpedo missed. The mark X torpedo was known to be touchy. If bumped hard the gyro would malfunction.

The year is 1918 and from the looks on the clothing the men are wearing it could be summer time.

The submarine L-8, designed by the Lake Torpedo Boat Company, was part of a secret project in 1918 by the U.S. Navy in WW I to trap German submarines. Along with the 4 masted schooner USS Charles Whittemore as a mother ship and decoy the pair roamed the Atlantic trying to lure German submarines to attack. The object was to use the L-8 to sink the German submarines.
The Whittemore towed the L-8 submerged so the submarine wouldn't be seen by the enemy and that the two wouldn't become separated from each other. The Whittemore carried food and fuel and torpedoes to resupply the L-8 as needed.
As it turned out by the time the Whittemore and L-8 arrived on station, all sides were using armed merchant men as decoys so the Germans and other ships would avoid any contact with the duo.
The war ended while the Whittemore and L-8 were on patrol with out firing a shot.
The L-8 ended its' life as a target off Newport, RI in 1926. She was the only ship blown up using the new top secret magnetic exploder. The Navy wouldn't allow any more tests using it due to budget constraints. This proved fatal folly early in WW II.

USS L-10 SS 50
USS L-10 SS 50 wearing her WW I "A".
The L-10 was heavily depth charged by the American destroyer USS Sterett in the Irish Sea after she had developed an oil leak. The Sterett thought he had found a German "U-Boat". L-10 managed to surface and identify herself before the destroyer managed to use her guns to try and sink her.

USS L-11 SS 51
USS L-11 SS 51
The USS L-11 sighted a U-boat on the surface. Not wanting to repeat the L-4 disaster of missing the shot, the Capt., Lt. A. C. Bennett, fired two torpedoes at the German, the second torpedo was launched five seconds after the first but faulty speed controls caused the second torpedo to run faster than the first and over took it and blew both torpedoes up. The U-boat dove and got away.

Racks of torpedoes
Racks of torpedoes for the war effort waiting to be loaded into boats. These are the Mark 7 torpedo, 17.7" in diameter and 17 feet long. This is typically the torpedo carried by all US subs into combat in WW I. The A, B and C class subs carried the Mark 7 Mod "D" that was 5 feet shorter to fit their tubes.
