Warship Wednesday, June 9, 2021: First of the Jeep Carriers

Here at LSOZI, we take off every Wednesday for a look at the old steam/diesel navies of the 1833-1954 period and will profile a different ship each week. These ships have a life, a tale all their own, which sometimes takes them to the strangest places. – Christopher Eger

Warship Wednesday, June 9, 2021: First of the Jeep Carriers

Here we see the unassuming yet near overloaded escort carrier, USS Long Island (CVE-1) underway off California on 10 June 1944, acting as an aircraft transport. Wearing Measure 32, Design 9a camo, she has 21 F6F Hellcats, 20 SBD scout bombers, and two J2F Duck utility planes on her flight deck. Commissioned 80 years ago this week, she was the prototype escort carrier in American service and made one hell of a beta test.

Laid down 7 July 1939, as the Type C3‑S‑A1 cargo freighter SS Mormacmail, under Maritime Commission contract for the Moore-McCormack Lines (Moore Mack), by the Sun Shipbuilding & Drydock Co., Chester, Pennsylvania, she launched 11 January 1940 and surely would have gone on to become any other merchantman had she not been acquired by the U.S. Navy on 6 March 1941 and entered service 2 June 1941 as Long Island (initially designated APV-1, but redesignated and commissioned as AVG-1, then later as Auxiliary Aircraft Carrier ACV-1 and CVE-1), with a lot of modifications from her original intended design.

Note flight deck under construction and temporary retention of her neutrality MKGS open. Lighter YC-301 is in the left background. NH 96711

Some 13,500 tons, she was 492 feet long and could accommodate 21 single-engine aircraft between her hangar deck and topside parking, or more than twice that many (as seen in the first image of this post) when being used as an aircraft transport.

As noted by DANFs:

In the tense months before Pearl Harbor, the new escort aircraft carrier operated out of Norfolk, conducting experiments to prove the feasibility of aircraft operations from converted cargo ships. The data gathered by Long Island greatly improved the combat readiness of later “baby flattops.”

No matter if you call them “jeep carriers,” or “Combustible, Vulnerable, and Expendable,” the escort carrier concept is one we have covered a few times in the past several years on WW. Besides one-off training carriers and prototype ships, four large classes of U.S.-built CVEs (Bogue, Sangamon, Casablanca, Commencement Bay) were cranked out during WWII, approaching 150~ hulls planned or completed for Uncle Sam and his Allies. And Long Island was the inaugural model.

FDR himself had a keen interest in her development and went to sea to view her in operation firsthand.

Augusta had President Franklin D. Roosevelt embarked to witness Long Island’s operations. Among the other ships present are USS Tuscaloosa (CA-37), partially visible at far right, and USS Meredith (DD-434), steaming astern of Long Island. 80-G-13074

Following the official U.S. entry into WWII after Pearl Harbor, Long Island got operational, escorting a convoy to Argentia.

Planes parked on the carrier’s snowy flight deck, behind the palisade, are Curtiss SOC-3A Seagull types, craft normally seen as floatplanes on cruisers and battleships of the day. 80-G-13129

Then, she qualified naval aviators on new types and made for the West Coast, because, while Hitler’s U-boats were beating a drum from Maine to Texas, things in the Pacific were even worse.

Reaching San Francisco on 5 June, Long Beach was attached to Task Force ONE under VADM William S. Pye to provide air cover for his four battleships headed to join Nimitz.

This is only six weeks past the Battle of Midway. She is painted in camouflage Measure 12 (Modified) and wears an unusual number on her bow: 751. 80-G-73390

With things growing hairy at a place called Guadalcanal, Long Island picked up two squadrons of Marine tactical aircraft, part of Marine Aircraft Group 23, and headed down to Henderson Field accompanied by the cruiser USS Helena (CL 50) and destroyer USS Dale (DD 353) to supply the first planes to the budding “Cactus Air Force.”

This plane is from Marine Fighting Squadron 211 (VMF-211), now best known as “The Wake Island Defenders” the last Navy or Marine Corps unit to operate the F2A in a front-line capacity. 80-G-12905

At 1700 on 20 August, the first Marines landed aircraft at Henderson Field– taking off from Long Island, some 200 miles to the southeast. They included 18 F4F Wildcats flown by the Bulldogs of VMF-223 (MAJ John L. Smith) and 12 SBD Dauntless dive bombers of the Red Devils of VMSB-232 (Lt. Col. Richard Mangrum). “A shout of relief and welcome went up from every Marine on the island,” reported LT. Herbert L. Merrill.

They flew their first combat missions from Guadalcanal the very next day and were in dogfights just 19 hours after landing.

Ordered back to the West Coast to serve as a training carrier– flattops in the Pacific of any type being exceedingly short at the time– Long Island avoided further brushes with combat but spent the better part of two years in this vital duty, alternating it with running aircraft to the forward areas as deck cargo. It was during this period that she was reclassified as an “Escort Carrier” and redesignated CVE-1.

Following VJ Day, she would continue serving as a Magic Carpet ride for returning GIs and bring back captured Japanese wonder weapons for technological analysis.

Japanese Army Type 4 Fighter, a Nakajima Ki-84 Hayate (U.S: “Frank”), painted in U.S. Navy colors onboard USS Long Island (CVE 1), 1945. Japan’s fastest fighter, Franks were the bane of B-29 squadrons over the Home Islands in the last years of the war. This example, serial number 1446, was captured at Clark Field during 1945 and shipped to the U.S. on Long Island late that year to be examined by the War Department. Sold off as surplus in 1952, it eventually made its way to the Tokko Heiwa Kinen-kan (Kamikaze) Museum in Japan, where it is the only surviving Ki-84 in the world.


Long Island received only one battle star for her World War II service and decommissioned on 26 March 1946 at Puget Sound Naval Shipyard. Struck 12 April 1946, she was sold to Zidell Ship Dismantling Co., Portland, Oregon., 24 April 1947, ostensibly for scrapping.

A survivor, she was converted by Albina Engineering & Machine Works, Portland, to become an immigrant carrier under the name of Nelly, slowly shuttling war-shook Europeans eager to quit the old world for the new from ports in Western Europe to Australia, with accommodations for 1,300 steerage class passengers.

MS Nelly is seen at sea

By 1955, she had been purchased by the Europe-Canada Line to, as noted by SS Maritime.com, “provide inexpensive student/migrant travel to Canada” with 20 First Class and 970 Tourist Class accommodations. She would sail as MS Seven Seas.

In 1963, she was again converted to a school ship for the University of the Seven Seas and World Campus Afloat (now Chapman University) then later become a floating dormitory in Rotterdam for Erasmus University, then for foreign workers in the 1970s.

Her usefulness long since passed, ex-SS Mormacmail/USS Long Island/SS Nelley/MS Seven Seas was towed to the breakers in Belgium in May 1977.

Little to nothing of Long Island remains today, and her name was never reused by the Navy, sadly. However, several of her squadrons, especially the 1942 Marine units, are still in existence.

Speaking of which, the image of the VMF-211 Buffalo crashed on her deck in July 1942 has gone on to have a life of its own, circulating far wider in its modified form than any other Long Island photo. It makes its rounds every May 4th.

The International Naval Research Organization is a non-profit corporation dedicated to the encouragement of the study of naval vessels and their histories, principally in the era of iron and steel warships (about 1860 to date). Its purpose is to provide information and a means of contact for those interested in warships.

With more than 50 years of scholarship, Warship International, the written tome of the INRO has published hundreds of articles, most of which are unique in their sweep and subject.
