style="text-align: justify;"><span style="color:#00008B">The L-class submarines were built to two distinctly different designs at four different shipyards. The two designs were from the Electric Boat Company (EB) of New York City (later Groton, CT.) and the Lake Torpedo Boat Company (LTB) of Bridgeport, CT. While very similar in military and operational capability, the two designs were vastly different in installed equipment, interior arrangement, and external appearance. EB chose to use individual muzzle doors for the torpedo tubes as opposed to its standard rotating bow cap. The reason for this design deviation is unknown. They reverted to the bow cap for the subsequent O-class. Lake had long standardized on individual muzzle doors. <p>The L-1 through L-4, and L-9 through L-11 were of the EB design and were built at an EB subcontractor, the Fore River Shipbuilding Co. of Quincy, MA. The Fiscal Year 1913 appropriations that paid for these boats also brought Simon Lake back into the submarine construction chain. The FY-10, 11, and 12 appropriations had given him only one submarine, FY-10's <a href="/index.php?title=G-3" title="G-3"><b>G-3</b></a>. This was mostly because of his very fragile financial situation and because he was struggling to complete and deliver the <a href="/index.php?title=G-class" title="G-class"><b>G-class</b></a> boats that had earlier been assigned to him. Having cleared the G-class construction log jam and having reorganized his company, Lake was assigned L-5 through L-8, although only the L-5 was actually built at the Lake yard in Bridgeport, CT. Desirous of once again having submarines built on the west coast the Navy contract stipulated that at least two boats be built there. Lake sub-contracted the L-6 and L-7 to Craig Shipbuilding in Long Beach, CA. The Bureau of Construction & Repair also wanted to get into the construction business as a means of offsetting the near monopoly that Electric Boat had acquired, and as a way to keep the exasperating Simon Lake at bay. BuC&R officials went to Lake and purchased a license from him to build the L-8 to his design at the Portsmouth Navy Yard in Kittery, ME. L-8 was to be the first in a long line of future submarines to be built at government owned Navy Yards. </p> The L-class made up the bulk of the submarines that the USN deployed to the European war zone during WWI. They operated out of the Azores and Bantry Bay, Ireland on anti U-boat patrols. While in the war zone off Ireland, the boats had the letter "A" painted on the fairwater directly adjacent to their name. This was intended to reduce confusion between the American boats and the <a rel="nofollow" class="external text" href="https://en.wikipedia.org/wiki/British_L-class_submarine"><b>Royal Navy's L-class submarines</b></a>. Not much came of the immense effort that was needed to deploy the American boats overseas, as they had no confirmed sinkings of enemy submarines or ships. However, it did drive home the fact that American coastal submarines were too small, too short ranged, and possessed poor habitability for North Atlantic waters.

In July of 1918 while patrolling in the Irish Sea, a large explosion rocked the L-2 about 25 feet on her beam. A torpedo aimed at her by a German U-boat had seemingly detonated prematurely. A periscope was sighted so the L-2 immediately submerged and made an unsuccessful attempt to ram the submarine. with her primitive sonar she 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 indeed attempted to fire upon the L-2, but another U-boat, the U-65, was unknowingly in the way and was hit by the torpedo meant for L-2. 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.</span></div> <p><a href="/index.php?title=L-2" title="L-2">See more L-2 photos</a> </p><p><span class="mw-default-size" typeof="mw:File"><a href="/index.php?title=File:Red_bar_sub.jpg" class="mw-file-description"><img src="/images/9/93/Red_bar_sub.jpg" decoding="async" width="1000" height="12" class="mw-file-element" data-file-width="1000" data-file-height="12" /></a></span> </p> <h3><span id="L-3_.28Submarine_No._42.2C_later_SS-42.29"></span><span class="mw-headline" id="L-3_(Submarine_No._42,_later_SS-42)"><big>L-3 (Submarine No. 42, later SS-42)</big></span></h3> <figure class="mw-halign-left" typeof="mw:File"><a href="/index.php?title=File:L3.jpg" class="mw-file-description" title="National Archives photo."><img alt="National Archives photo." src="/images/4/43/L3.jpg" decoding="async" width="500" height="415" class="mw-file-element" data-file-width="370" data-file-height="307" /></a><figcaption>National Archives photo.</figcaption></figure> <div style="text-align: justify;"><span style="color:#00008B">L-3 with sailing yachts, early in her career, approximately 1916.

The boat is maneuvering alongside a pier, getting ready to tie up after a run at sea. Lines have been flaked out on deck and the two sailors on the bow seem to be ready to throw a "heevie", a small diameter line with a weight on the end. It is used to throw over to a pier or tender, so that the large, heavy mooring line can then be pulled over and secured.

There is no date on the photo but the assumption is circa 1918. The L-10 was one of the best American subs working out of Ireland. <p>LT Vincent Arthur Clarke, Jr. was sent for submarine training at New London, Connecticut. Upon graduation he was assigned to submarine duty and sent to the Azores. From there he was made the commanding officer of the L-10, probably relieving LT Newbold T. Lawrence Jr. as CO. The L-10 operated out of Bantry Bay, Ireland for the duration of the war. </p><p>This command garnered Clarke a Navy Cross for his persistence in making the L-10 one of the "hot running boats" in WW I, racking up over 1700 hours out on patrol in pursuit of the enemy. War patrols in WW I were only an average of 10 days duration due to the sub's limits on food, water and fuel. </p><p>LT Clarke is probably the officer on the bridge in this photo as the L-10 backs away from her mooring. The crew look to be stowing the mooring lines in preparation for possibly heading out on a war patrol looking for German submarines. </p><p><a href="/index.php?title=L-10" title="L-10">See more L-10 photos</a> </p><p><span class="mw-default-size" typeof="mw:File"><a href="/index.php?title=File:Red_bar_sub.jpg" class="mw-file-description"><img src="/images/9/93/Red_bar_sub.jpg" decoding="async" width="1000" height="12" class="mw-file-element" data-file-width="1000" data-file-height="12" /></a></span> </p> <div style="text-align: justify;"><span style="color:#000000"> <h3><span id="L-11_.28Submarine_No._51.2C_later_SS-51.29"></span><span class="mw-headline" id="L-11_(Submarine_No._51,_later_SS-51)"><big>L-11 (Submarine No. 51, later SS-51)</big></span></h3> </span></div> <figure class="mw-halign-left" typeof="mw:File"><a href="/index.php?title=File:L-11_from_port_on_trials.jpg" class="mw-file-description" title="Photo NH 51173 courtesy NHHC."><img alt="Photo NH 51173 courtesy NHHC." src="/images/thumb/3/3b/L-11_from_port_on_trials.jpg/500px-L-11_from_port_on_trials.jpg" decoding="async" width="500" height="379" class="mw-file-element" srcset="/images/thumb/3/3b/L-11_from_port_on_trials.jpg/750px-L-11_from_port_on_trials.jpg 1.5x, /images/thumb/3/3b/L-11_from_port_on_trials.jpg/1000px-L-11_from_port_on_trials.jpg 2x" data-file-width="1243" data-file-height="943" /></a><figcaption>Photo NH 51173 courtesy NHHC.</figcaption></figure> <div style="text-align: justify;"><span style="color:#00008B">L-11 running builder's trials in Cape Cod Bay off Provincetown, MA., summer of 1916.

The unique shape of the bow planes pivot housings and the unique shaped “bullnose” on the tip of the bow are identifiers of the EB design for this class. The two flat rectangular covers, one on top of the other over the bow planes pivots can be seen. This cover was unique to the L-1, L-2, L-3 and L-4 and then again with the L-9, L-10, and the L-11. Submarines L-5 through L-8 were built to the Lake Co. design and did not have these pivot covers. This variant of the L-class of submarine were commissioned by late 1916. The L-6 thru L-8 variant were commissioned in 1917. L-5 was commissioned in 1918. <p>Both submarines have a tall forward radio mast. In looking in other archives we have seen only the L-1 with such a mast. So, possibly one of these two vessels could be the L-1 but it could just be coincidence that there only exists one image, other than this one, with these masts. Radio was new and trials were being made all the time. </p><p>Neither submarine have any sign of having SC tube listening gear installed at this point. So, a possible date is closer to commissioning, perhaps a late 1916 or early 1917. But for sure this is before the U.S. entered WW I on April 6, 1917. The submarines still are using the old-fashioned pre-war canvas bridge shelters that proved too flimsy to withstand the pressures of diving with it erected. They were too time consuming to try and take down in actual war time conditions. </p><p>The British, having been at war with Germany for two years, taught their American cousins a lot of practical things about actual submarine warfare including the development and use of the metal chariot bridge surround that could remain in place while diving and withstand those pressures. Soon almost all U.S. submarines had this revision installed. </p><p>Once these subs reached Europe, the British, to avoid confusing their L-class submarines with the American L-class, required the Americans to paint an "A" in front of their numbers. All combatants still wore hull identification at this time. In later conflicts all ID was painted out so an enemy could not keep track of sub movements, this is even done to this day. </p> These two submarines are moored to a monitor-type tender that is also not identified but could possibly be the USS Tonopah (BM-8). Three sailors are standing on the tender's deck. There also seem to be at least two people each on the submarine's decks.</span></div> <p><a href="/index.php?title=General_L-boat_photos" title="General L-boat photos">See more L-class photos</a>
