USS Chicago (CA-136) - Post-Vietnam

Post-Vietnam

Arriving home on 8 July, the ship underwent a local availability before entering Long Beach Naval Shipyard on 25 August for a Complex Overhaul. During this refit, Chicago received new digital fire control systems, replacing the old analog computers, installed new missile launchers, and expanded her electronics equipment.

On 15 May 1973, Chicago began carrying out six months of sea trials, tests, and training evolutions. New equipment and combat coordination procedures were also implemented, extending the cruiser's operational readiness date to 14 December. Finally, after refresher training, fleet exercises, and weapons load-out, the cruiser departed for another WestPac deployment on 21 May 1974. After arrival at Subic Bay on 15 June, the ship prepared for an extended cruise with Fanning, George K. MacKenzie, and Passumpsic. Designed to counter the Soviet Navy's presence in Somalia and Aden on the Indian Ocean, the low-key port visits were intended to demonstrate that "the Indian Ocean is not a Russian lake".

Departing Subic Bay on 25 June, the squadron passed through the Straits of Molocca on 2 July and arrived at Karachi, Pakistan six days later. Underway on 13 July, Chicago and her escorts began a month long at sea period, "showing the flag" in the Arabian Sea and the Gulf of Aden, before arriving at Mombassa, Kenya on 9 August. A week later, in an effort to influence Russian negotiations for basing rights in the Mauritius Islands, the squadron conducted a diplomatic port visit to Port Louis. Toward this end, Chicago embarked several Mauritian government officials on 21 August for a two-day cruise to Rodrigues Island. Departing on 23 August, the ships returned to Subic Bay, via Singapore, for upkeep on 11 September.

Following a visit to Hong Kong in early October, the cruiser spent the next month conducting training and fleet exercises in the Philippines area until getting underway for Guam on 17 November. After a week at Apra Harbor, the ship departed on 29 November for San Diego. Arriving home on 14 December, the ship remained in port for leave, repairs, and upkeep into March 1975. Technical inspections and equipment modifications, interspersed with a visit by a delegation of French officials, lasted until April when the ship conducted interim refresher training in the southern California operating areas.

Following a series of missile tests in late May, and fleet exercises with Pacific naval units, the cruiser visited Seattle for the Fourth of July celebrations. After a visit to Vancouver the following week, Chicago returned to San Diego to begin overhaul preparations. From 9 September to 24 October, the cruiser underwent a major restricted availability as repairs were conducted to fuel tanks, boiler casings, and the main propulsion plant. Additional upkeep, tender availability, and type training continued through the new year as the cruiser prepared for another deployment. In February 1976, personnel in the Operations department underwent extensive team training in anti-air, anti-submarine, and electronic warfare in preparation for a fleet exercise in March. That operation, exercise "Valiant Heritage", took place from 2–11 March with forces from Canada, the United Kingdom, New Zealand, and the United States.

Following a month in port, and several service inspections, Chicago left San Diego on 13 April to deploy to the Western Pacific. Sailing with an amphibious group the cruiser conducted multi-ship exercises, both before and after Pearl Harbor, and arrived at Yokosuka on 3 May. Task group exercises with Midway, "Multiplex 2-76" from 19–25 May and "Multiplex 3-76" in the South China Sea from 4–7 June, and port visits to Subic Bay and Keelung, occupied Chicago through June. After a midshipmen cruise from Yokosuka to the Philippines in early July, the cruiser began an import period lasting until 2 August.

On 4 August, the cruiser participated in "Multiplex 1-7T", followed by a successful missile firing exercise off Poro Point, Luzon on 7 August. Returning to Subic Bay for two weeks of upkeep, the cruiser sailed for Hong Kong on 22 August. Arriving three days later, after avoiding a third typhoon, the ship spent six days in that liberty port. Leaving Hong Kong on 31 August, Chicago joined rendezvous with Enterprise for a war-at-sea exercise lasting until 8 September, before returning to Subic for a lengthy upkeep period. Repainting the exterior, and interior improvements lasted until 27 September, when the cruiser got underway for home. Stopping at Guam on 1 October to refuel, and Pearl Harbor on 9 October for a dependents cruise, the ship finally returned to San Diego on 16 October.

The cruiser remained in port, receiving boiler repairs and equipment upgrades, until 23 February when the ship began post-repair sea trials and crew training. Following inspections, and ordnance loadout at Seal Beach on 3 March, Chicago began a regular schedule of training operations out of San Diego. These exercises, including helicopter pad training, simulated missile and torpedo attacks, and other similar drills, continued until 6 September, when the ship got underway for her eighth WestPac tour.

Chicago arrived in Subic Bay on 30 September, after multi-ship exercises that included four missile shots while underway, to begin a series of operations with the 7th Fleet. Missile shots and convoy exercises off Mindoro, a barrier exercise off Buckner Bay, and visits to Yokosuka, Keelung, and Hong Kong lasted until late November. On 4 December, after a rendezvous with Kitty Hawk, the cruiser began operations in the Sea of Japan. Helicopter and underway replenishments were interrupted two days later, when the formation was circled by two Soviet Tupolev Tu-16 "Badgers", but exercises continued until 8 December. Departing the area, Chicago steamed south to Subic Bay, for sonar exercises with Queenfish, arriving at Singapore on 23 December. After the holidays, the cruiser moved to Phattaya Bay, Thailand on 30 December.

Departing 4 January 1978, the cruiser visited Subic Bay and Hong Kong before starting a month of exercises in the Philippine Sea. Gunfire exercises, helicopter operations, unreps, and other drills, including a real man overboard rescue on 28 February, lasted until 4 March, when Chicago moored at Manila. After repairs and upkeep, the ship steamed for Guam on 16 March, arriving five days later to refuel, before arriving in Pearl Harbor on 31 March.

After returning to San Diego on 7 April, the ship remained in upkeep status until 24 July 1978, when the cruiser moved to Long Beach to start a regular overhaul. Repairs at the Long Beach Naval Shipyard lasted until 18 October, when the cruiser conducted two days of sea trials. Finishing work continued until 25 October, when Chicago departed the shipyard. After two days of operations with England and Darter, the cruiser moved back to San Diego to begin a regular schedule of training exercises. These short cruises, concentrating on gunnery and underway training, lasted through February 1979. A number of propulsion and electronic service inspections were also conducted. On 5 March, during exercises off southern California, the cruiser also earned her eleventh consecutive Missile "E".

After a month long pre-deployment period, the cruiser departed on 30 May for the cruiser's final cruise to the Western Pacific. Chicago escorted the aircraft carrier Kitty Hawk and her battle group to Pearl Harbor, conducting exercises with Jouett, Lang, and Wabash along the way, before steaming on to Subic Bay on 13 June. Fleet exercises off Okinawa, and a port visit to Pusan, South Korea, at the end of July, were followed by refugee surveillance in the South China Sea. There, along with other 7th Fleet ships, she helped rescue Vietnamese refugees fleeing the mainland, picking up five herself.

Escort duties for Kitty Hawk continued through September when, on 6 October, she sailed for Australia. On 15 October, after memorial services for two cruisers lost in the Solomon Islands battles during World War II, Canberra and the earlier Chicago, the cruiser began two weeks of exercises in the Coral Sea. After the exercise, involving seven U.S. ships and twenty Australian and New Zealand vessels, the ship visited Sydney, Australia, for a week long port visit. Returning to San Diego on 17 December, via Subic Bay and Pearl Harbor, the cruiser began preparations for inactivation.

A pre-decommissioning inspection classified the cruiser as unfit for further economical naval service, due the high cost of modernization required, and on 1 March 1980, Chicago was decommissioned at San Diego. Towed to the Inactive Ship Facility at Bremerton, Washington, the ship was held in reserve until 8 February 1989. Stripped of equipment by 11 August, the hulk was sold for scrap to Southwest Recycling, Inc., Terminal Island, California on 9 December 1991. The anchor was saved and placed on display at Navy Pier on 11 November 1995.
