USS Kitty Hawk — the Battle Cat of North Island.

When the dredging crews finished cutting the San Diego main ship channel to 42 feet, there was only one ship in the United States Navy that required it. USS Kitty Hawk had been commissioned on April 29, 1961, at the New York Shipbuilding yards in Camden, New Jersey, and she was too wide for the Panama Canal locks by twenty feet — 130 feet at the beam against the Canal's maximum of 110. The only route from the Atlantic to the Pacific was south past the equator, around Cape Horn, through the Drake Passage, and north again up the Chilean coast — the same waters that had broken sailing ships for three centuries. When she entered San Diego harbor that spring with a Navy band on the pier playing "California, Here I Come," she was 1,047 feet of newly commissioned flight deck and the most capable conventionally powered carrier in the world. The channel had been cut for her alone. She arrived as expected.

She was the lead ship of the Kitty Hawk class, an improvement on the four Forrestal-class supercarriers that had entered service between 1955 and 1959 as the Navy's first carriers designed from the keel up for jet aviation. The Forresters had established the form; the Kitty Hawks were built to correct what operating them had revealed. The new design moved all four flight-deck elevators to the deck edge, clearing the angled landing area that a Forrestal elevator had straddled and forced into workarounds — a problem small on paper, ruinous in tempo. Below decks, the hangar was reorganized for heavier aircraft. Her initial air wing at North Island included the Douglas A-3 Skywarrior — among the heaviest aircraft ever operated from a carrier deck, built from the outset as a nuclear strike platform — alongside the A-4 Skyhawk and the F-8 Crusader. She carried the weapons that defined the Cold War at sea: the ability to deliver a nuclear or conventional strike from any patch of open ocean within the Pacific.

The strategic logic of homeporting her at Naval Air Station North Island had been accumulating since the 1920s, when the first American carriers made the Coronado peninsula their West Coast base. By 1961 the argument was closed. North Island sat three days' steaming from Pearl Harbor and less than two weeks from the straits of the Western Pacific — the Taiwan Strait, the Luzon Strait, the Korea Strait — where the Cold War's theoretical crises would become real ones. In the same months that Kitty Hawk rounded Cape Horn, the Berlin Crisis escalated to the construction of the wall, Soviet nuclear tests resumed after a three-year moratorium, and the Navy was being asked to plan options across a spectrum running from blockade to general war. A carrier of her size and capability homeported at North Island could be at sea and generating strikes within hours, not weeks. The map pointed to Coronado. The Navy followed the map.

The theoretical war became real in 1964. After the Gulf of Tonkin incidents authorized American combat operations against North Vietnam, Kitty Hawk became a recurring presence in the waters off the Indochina coast. Her pilots flew strikes under Operation Rolling Thunder and later Linebacker against radar-directed antiaircraft concentrations denser than anything American naval aviators had encountered since 1945. The ship carried the weight that accumulates across years of combat deployment — aircraft and pilots that did not return, the manifest written and rewritten between WestPac tours. In October 1972, during a prolonged deployment to the Gulf of Tonkin, racial tensions between Black and white enlisted sailors erupted into three days of fighting that injured dozens of crew members. The incident prompted a Navy-wide review of shipboard conditions, command climate, and promotions equity. Kitty Hawk was not the only ship carrying these pressures; she was the ship on which they became impossible to ignore.

San Diego counted the years between deployments. Between combat tours, Kitty Hawk came back to North Island — to the dry docks at Naval Station San Diego, the aircraft overhaul shops on Coronado, the families who had settled from Point Loma to Chula Vista while the ship was somewhere in the Philippine Sea. The port had organized itself around carrier operations since USS Langley first called North Island home in the early 1920s, and by the time the Battle Cat arrived it had built an entire support economy — defense contractors along the waterfront, neighborhoods that emptied when a carrier deployed and refilled when she came home, a city that measured the calendar in WestPac schedules. More than three decades of that rhythm accumulated between 1961 and 1998. The 42-foot channel that the harbor dredgers had cut to receive her had become, in the way that purpose-made infrastructure always does, the permanent signature of her presence.

In 1998, after thirty-seven years at North Island — longer than most of her crew members had been alive — Kitty Hawk sailed out of San Diego Bay for the last time. The Navy had selected her to replace USS Independence at Fleet Activities Yokosuka — the forward-deployed carrier station that kept an American flight deck in the Western Pacific without the multi-week transit a homeported ship required in a crisis. Independence had held the Yokosuka berth since 1991 and was approaching the end of her service life; Kitty Hawk, conventionally powered and with sufficient hull life remaining, was chosen for the assignment. She took the westward heading she had taken on every combat deployment, with North Island receding astern, and did not return. At Yokosuka she served another decade, operating within sight of the former Imperial Japanese naval base that had once dispatched the carrier fleet to Pearl Harbor, flying the same ensign she had first raised in Camden in 1961.

She was decommissioned at Bremerton, Washington, in May 2009 — forty-eight years of active service, the longest career of any conventionally powered carrier in the United States Navy. For most of those forty-eight years, her home had been the harbor that rearranged itself to receive her. The pier she first tied up at in the spring of 1961 still stands. The North Island flight line still runs aircraft. The same summer swells roll through the same 42-foot channel where a Navy band played one morning and a 1,047-foot ship moved into its berth and stayed a generation. You could sail it tonight.
