Essex was a class of aircraft carriers of the United States Navy, which constituted the 20th century's most numerous class of heavy warships, with 24 ships built. These included members of the "long-hull" Ticonderoga variant/subclass, which some consider a separate class in their own right. Thirty-two were originally ordered, however six were cancelled before construction, and two were cancelled after construction had begun. The Essex class, along with the three Midway-class carriers, were the backbone of the Navy's combat strength in the years after World War II, until the supercarriers began to come into the fleet in numbers during the 1960s and 1970s.

Overview

The preceding Yorktown-class carriers formed the basis from which the Essex class was developed. Designed to carry a larger air group, and unencumbered by pre-war naval treaty limits, the USS Essex (CV-9) was over sixty feet longer, nearly ten feet wider in beam and more than a third heavier. A longer, wider flight deck and a deck-edge elevator facilitated more efficient aviation operations, enhancing the ship's offensive and defensive air power. Machinery arrangement and armor protection was greatly improved from previous designs. These features, plus the provision of more anti-aircraft guns, gave the ships much enhanced survivability. In fact, none of the Essex-class carriers were lost and two of them, Franklin (CV-13) and Bunker Hill (CV-17), came home under their own power even after being grievously damaged.

US carriers had the same amount of deck armor as that carried by their British counterparts. While debates raged, and continue to this day, regarding the effect of placement (flight deck level on British ships vs. hangar deck level on American ships), British designers' comments tended to disparage the use of deck armor, and serious historians, such as D.K. Brown in Vanguard to Trident, generally see the American arrangement to have been superior, until the larger size of the first supercarriers necessitated a deeper hull, and thus moving the strength deck to the flight deck.

Development

After the abrogation by Japan from disarmament treaties, the U.S. took a realistic look at its naval strength. With the Naval Expansion Act of Congress passed on May 17, 1938, an increase of 40,000 tons in aircraft carriers was authorized.

CV-9 was to be the prototype of the 27,000-ton (standard displacement) aircraft carrier, considerably larger than the Enterprise (CV-6) yet smaller than the Saratoga (CV-3) (a battlecruiser converted to a carrier). These were to become known as the Essex-class carriers, although this classification was latter dropped in the 1950s. On September 9, 1940, eight more of these carriers were ordered and were to become the Hornet (CV-12), Franklin (CV-13), Ticonderoga (CV -14), Randolph (CV-15), Lexington (CV-16), Bunker Hill (CV-17), Wasp (CV-18) and Hancock (CV-19).

It should be noted that the Lexington, Wasp, Hornet and the Yorktown names were not their originally intended ones, but were used in line with the Navy’s intent to carry on the traditions of their fighting predecessors who were lost during combat in 1942. It should also be noted that of the original 13 ordered "Essex-class" ships, several of them, the Ticonderoga (CV-14), Randolph (CV-15), Hancock (CV-19), and Boxer (CV-21) were modified during construction as part of the "long hull" group, with the bow extended into a "clipper" shape to provide room for additional anti-aircraft armament.

Nineteen more Essex-class ships were ordered or scheduled, starting with ten of them on August 7, 1942. Only two of the ships, the Bon Homme Richard (CV-31) and the Oriskany (CV-34) were laid down as Essex "short hull" keels. The remainder became the Ticonderoga or "long hull" class ships. CV-16 was originally laid down as the "Cabot", but was renamed "Lexington" during construction after the Lexington (CV-2) was lost in the Battle of the Coral Sea in May 1942; she was commissioned on February 17, 1943. CV-10, originally to be named the "Bon Homme Richard", was renamed after the Yorktown (CV-5) was lost at the Battle of Midway on June 7, 1942. CV-18's name was changed from "Oriskany" after the Wasp (CV-7) was sunk in September 1942 in the South Pacific while escorting a troop convoy to Guadalcanal, and the CV-12's name was changed from "Kearsarge" after the Hornet (CV-8) was lost in October 1942 in the Battle of Santa Cruz Islands. is the 219th day of the year (220th in leap years) in the Gregorian calendar. ...

Design

In drawing up the preliminary design for USS Essex (CV-9), particular attention was directed at the size of both her flight and hangar decks. Aircraft design had come a long way from the comparatively light planes used in carriers during the 1930s. Flight decks now required more takeoff space for the heavier fighters and bombers being developed. Most of the first-line carriers of the pre-war years were equipped with flush deck catapults, but owing to the speed and size of these ships very little catapulting was done—except for experimental purposes. The 1930s (years from 1930–1939) were described as an abrupt shift to more radical and conservative lifestyles, as countries were struggling to find a solution to the Great Depression, also known as the World Depression. ... u suk usuk u suk u suk u suk u suk u suk u suk u suk u suk usuk suk suk suk suk suk suk suk suk suk suk suk suk suk suk suk suk{| class=wikitable |- ! header 1 ! header 2 ! header 3 |- | row 1, cell 1 | row 1...

With the advent of war, airplane weights began to go up as armor and armament got heavier; crew size aboard the planes also increased. By the war’s end in 1945, catapult launchings would become more common under these circumstances with some carrier commanding officers reporting that as much as 40% of launchings were effected by the ships’ catapults.

The hangar area design came in for many design conferences between the naval bureaus. Not only were the supporting structures to the flight deck to carry the increased weight of the landing and parked aircraft, but they were to have sufficient strength to support the storing of spare fuselages and parts (50% of each plane type aboard) under the flight deck and still provide adequate working space for the men using the area below.

A startling innovation in the Essex was a port-side deck-edge elevator in addition to two inboard elevators. Earlier, experiments with a ramp arrangement between the hangar and flight decks, up which aircraft were hauled by crane proved too slow. The Navy's Bureau of Ships and the Chief Engineer of A.B.C. Elevator Co., designed the engine for the side elevator. Essentially, it was a standard elevator, 60 by 34 ft (18 by 10 m) in platform surface, which traveled vertically on the port side of the ship. The design was a huge success which greatly improved flight deck operations over carriers prior to the Essex. The United States Navys Bureau of Ships (BuShips) was established by Congress on June 20, 1940, by a law which consolidated the functions of the Bureau of Construction and Repair and the Bureau of Engineering. ...

Since there was no large hole in the flight deck when the elevator is in the ‘down’ position, a critical factor if the elevator were to ever become inoperable during combat operations, the development of the side elevator was a significant improvement in flight operations. Its new position made it easier to continue normal operations on deck, irrespective of the position of the elevator. The elevator also increased the effective deck space when it was in the ‘up’ position by providing additional parking room outside the normal contours of the flight deck, and increased the effective area on the hangar deck by the absence of elevator pits. In addition its machinery was less complex than the two inboard elevators, requiring about 20% fewer man-hours of maintenance.

Ongoing improvements to the class were made, particularly with regards to the ventilation system, lighting systems and the trash burner design and implementation.

These carriers had better protecting armor than their predecessors, better facilities for handling ammunition, safer and greater fueling capacity, and more effective damage control equipment.

The tactical employment of U.S. carriers changed as the war progressed. In early operations, through 1942, the doctrine was to operate singly or in pairs, joining together for the offense and separating when on the defense—the theory being that a separation of carriers under attack not only provided a protective screen for each, but also dispersed the targets and divided the enemy’s attack. Combat experience in those early operations did not bear out the theory and new proposals for tactical deployment were the subject of much discussion. Military tactics (Greek: TaktikÄ“, the art of organizing an army) are the collective name for methods for engaging and defeating an enemy in battle. ...

As the new Essex- and Independence-class carriers became available, tactics changed. Experience taught the wisdom of combined strength. Under attack, the combined anti-aircraft fire of a task group's carriers and their screen provided a more effective umbrella of protection against marauding enemy aircraft than was possible when the carriers separated.

When two or more of these task groups supported each other, they constituted a fast carrier task force.

With the evolution of the fast carrier task force and its successful employment in future operations.

"Sunday Punch"

The pride of the carrier known as the "Sunday Punch" was the offensive power of 36 fighters; 36 dive bombers and 18 torpedo planes. The F6F Hellcat would prove to be superior to the Japanese Zero. It was twice as powerful as the Zero and could therefore climb higher and fly faster. Due to the increase in power, the Hellcat could carry an enormous amount of firepower. The Hellcat boasted six .50 caliber (12.7 mm) machine guns with a rate of fire of over 1000 rounds per minute. The SB2C-1 Helldiver, was a dive-bomber with a capacity of 2650 pounds (1,200 kg) of ordnance or one torpedo. Designed solely as a torpedo plane, Avenger (TBF-1) was produced by Grumman Aircraft. Some Essex-class carriers, such as the Bunker Hill (CV-17), also included squadrons of F4U Corsairs in Fighter-Bomber squadrons (VBFs), the precursor to modern Fighter-Attack (VFA) squadrons.

Guns, radar and radios

The defensive plan for the carriers was to use radio and radar in a combined effort to concentrate anti-aircraft fire. For other uses, see Radar (disambiguation). ...

The ship boasted four twin 5 in (127 mm) gun turrets, seventeen quad-barrel, 40 mm, anti-aircraft guns and 65 single, 20 mm, close-in defense guns. With a range of ten miles and a rate of fire of fifteen rounds per minute, the 5-inch guns fired the deadly VT shells. The VT shells, known as proximity fuzed-shells, would detonate when they came within 70 feet (21 m) of an enemy aircraft. The 5-inch guns could also aim into the water, creating waterspouts which could bring down low flying aircraft such as torpedo planes. The Bofors 40 mm guns were a significant improvement over the 1.1"/75 (28mm) guns mounted on the earlier Lexington and Yorktown classes.

The Essex class also made use of advanced technological and communications equipment. The Mark 4 sweeping radar was installed but could not track incoming low-level intruders and was quickly replaced with the improved Mark 12 radar. The Plan Position Indicator (PPI) radar was used to keep track of ships and enabled a multi-carrier force to maintain a high-speed formation at night or in foul weather. The new navigational tool known as the Dead Reckoning Tracer was also implemented for navigation and tracking of surface ships. The Identification Friend or Foe (IFF) was used to identify hostile ships and aircraft, especially at night or in adverse weather. The four-channel very high frequency (VHF) radio permitted channel variation in an effort to prevent enemy interception of transmissions. A four-channel radio also allowed for simultaneous radio contact with other ships and planes in the taskforce.

The "long-hull" Essexes

USS Boxer (CV-21).

Throughout the very large program to build Essex-class aircraft carriers, modifications were constantly made. The number of 40 mm and 20 mm anti-aircraft cannons was greatly increased, new and improved radars were added, the original hangar deck catapult installation was taken out completely, the ventilation system was massively revised, details of protection were altered and hundreds of other large and small changes were executed. In fact, to the skilled observer, no two ships of the class looked exactly the same.

Beginning in March 1943, one visually very significant change was authorized for ships then in the early stages of construction. This involved reshaping the bow into a rather elegant "clipper" form to provide deck space for two 40 mm quadruple gun mountings, thus greatly improving forward air defenses. Thirteen ships were completed to this "long-hull", or Ticonderoga, class. Four of these were finished in 1944, in time to join their short-hull Essex-class sisters in Pacific combat operations. The rest went into commission between early 1945 and late 1946.

Their construction greatly accelerated, the Essex class formed the backbone of the Navy's mobile air striking power during the climactic years of the Pacific War. Due to their large and spacious hangars, and the innovation of the angled flight deck, they could easily accommodate jet aircraft. With their larger contemporaries of the Midway class, these carriers sustained the Navy's air power through the rest of the 1940s, during the Korean War era and beyond.

Five of the long-hulls were laid up in 1946–47, along with all of the short-hulls. Eight stayed on active duty to form, with the three much larger Midways, the backbone of the post-war Navy's combat strength. Though the Truman administration's defense economies sent three of the active Essexes into "mothballs" in 1949, these soon came back into commission after the Korean War began.

Even after the arrival of the Forrestal-type "super carriers", the Essex class remained vital elements of naval strength.

Korean War and subsequent Cold War needs ensured that twenty-two of the twenty-four ships had extensive post-World War II service, all initially with attack air groups. As bigger carriers entered the fleet, 18 of the Essex class were reassigned to the anti-submarine warfare (ASW) mission. Unmodernized ships began to leave active service in the late 1950s, but three had about a decade of additional duty as helicopter assault transports for the Marine Corps. The updated units remained active until age and the increasing fleet of supercarriers drove them from the high seas from the late 1960s into the middle 1970s. However, one of the very first of the type, Lexington (CV-16), ran on until 1991 as the Navy's training carrier. She then became a museum, a new role that also employs three of her siblings, Yorktown (CV-10), Intrepid (CV-11), and Hornet (CV-12).

Of the six unmodernized long-hull Essexes, three decommissioned in the late 1950s and early 1960s and were promptly reclassified as aircraft transports (AVT), reflecting their very limited ability to safely operate modern aircraft. The other three, converted to Landing Platform Helicopter (LPH) amphibious assault ships, were active until about 1970. The two least modernized units went into reserve in the mid-1960s, and the rest passed out of the active fleet between 1969 and 1976.
