During the afternoon watch on 14 January 1944, Zuni left her position in the formation and came alongside, transferring Sea1c Hugh W. Morris, diagnosed with appendicitis, to Lynx, for medical treatment.

[4] Less than an hour before the end of the forenoon watch, 11:03, on 18 January 1944, Sea2c Maurice L. Bosshart, V-6, USNR, a passenger traveling in Lynx for further transportation to YRD(M)-1 for duty, fell overboard.

Shortly before the end of the first dog watch on 28 January, at 17:55, Lynx embarked Sergeant Claude E. Rudy, USMC, a passenger in the tug Zuni, who had been diagnosed with appendicitis.

Rudy and Sea1c Morris, the two recovering appendicitis patients, back to Zuni, while the tug returned the cargo ship's Franklin life buoy that had been put in the water during the unsuccessful attempt to save Sea2c Bosshart.

Underway two days later, she moored at Pier 25, San Francisco, on 8 May, where she began a period of minor repairs and alterations in the hands of the General Engineering Co. on 9 May.

Shifting to the General Engineering & Drydock Company's yard at Alameda, on 16 May, she entered the floating dry dock YFD-19, where her bottom was scraped and painted and paravane gear installed, 16–19 May.

Underway to calibrate her radio direction finder that afternoon, she anchored in San Francisco Bay when that task was done, pausing only until the morning of 16 October, when she sailed for Oahu, Lynx, convoy commander, taking departure with Lignite in tow and accompanied by YF-450.

She unloaded cargo at X-5 until 7 November, at which point she shifted berths to X-11, mooring alongside Durham Wright at 09:47, that ship's place taken by another freighter, Joel Palmer, at 18:12.

[4] PS-160T's voyage proceeded without incident until 12:32 on 13 November 1944, some 100 mi (160 km) west-southwest of Los Angeles, Calif., Ardent's sonar picked up a submarine contact.

While the ships in company took evasive action on signal from the convoy commodore in U. S. Grant, Ardent carried out two more attacks and the frigate dropped 13 depth charges.

[4] Postwar research revealed the sunken boat to be Japanese submarine I-12, Commander Kudo Kaneo, that had sailed from the Inland Sea on 4 October 1944, to disrupt American shipping between the west coast and the Hawaiian Islands.

[4] With the convoy commodore riding in Lynx and the vice-commodore in the auxiliary tug ATA-177, the assembly of ships proceeded on their voyage with Pratt and Rombach and PC-1134 carrying out anti-submarine patrolling on the starboard and port flanks, and ahead, respectively.

Detached two hours into the mid watch on 28 January, PC-1134 proceeded ahead to rendezvous with additional ships slated to join the convoy off Biak.

The submarine chaser returned, shepherding her new charges, that afternoon, and after towing assignments with the new arrivals had been taken-up, the convoy resumed its slow speed of advance, 5 kn (9.3 km/h; 5.8 mph), at 23:38, bound for the Philippine Islands.

[4] Reaching San Pedro Bay, Leyte, half-way through the morning watch on 5 February 1945, the convoy dispersed shortly after its arrival, Lynx turning over YO-164 to the rescue tugs ATR-36 and ATR-86 before dropping anchor in berth 91.

She got underway at 08:00 on 13 March, in accordance with orders from the Port Director at Tolosa Beach, Leyte, to rendezvous with Convoy IG 103, thence to proceed to Hollandia.

Almost three hours into her voyage, however, Lynx received a dispatch from Commander Task Force 75, in accordance with which she reversed course and returned to San Pedro Bay, dropping anchor in berth 484, upon arrival.

Three hours into the mid watch on 25 April, the convoy received a Commander Task Force 51 secret dispatch “warning of submarine activity in our immediate vicinity.” Ordered to divert from their present course and “to proceed via new reference points” to their destination, UOK 2 did so.

The warning may have been related to the activities of the Japanese submarine RO-109, Lt. Nakagawa Hiroshi, which was sunk with all hands, 56 dead all told, by the high speed transport Horace A. Bass, that was escorting another Okinawa-bound convoy, after three attacks during the second dog watch on 25 April.

Ships in the vicinity, as well as shore defenses, shot down an aircraft identified as a Betty (twin-engine, land-based bomber), splashing it about 1,000 yd (910 m) on Lynx's port beam.

[4] Lynx stayed at battle stations, with Japanese planes reported overhead and “suicide boats at large in the anchorage,” through the mid watch on 28 April 1945, her sailors noting “considerable rifle fire from nearby ships...presumed to be shots fired at possible suicide [assault demolition] boats.” With receipt of a Flash White at 04:16, the ship secured from general quarters and ceased making smoke, the continued discharging cargo into lighters alongside.

Securing from battle stations at 02:25 on 29 April 1945, after receiving a Flash White, the ship stood to general quarters three more times that day, 04:29–05:10, 07:51–08:03 and 21:05–23:58, continuing the unloading process in between the first two alarums, 05:10-07:51.

[4] Shifting her berth the following morning, 3 May 1945, Lynx provided 40-millimeter ammunition to the Landing Ship Medium (Rocket) LSM(R)-192 an hour before the end of the forenoon watch.

[4] After taking on fresh water from Abatan and fuel from tanker Chotauk on 11 May 1945, Lynx sailed for the west coast of the United States the following morning.

Both vessels were operating well outside of the restricted zone, which is provided for such operations, at Kaneohe Bay, but both showed an utter disregard for the rules of the road and safety at sea, by apparent unnecessary re-crossing this vessel’s bow.”[4] Reaching San Francisco with no further incident on 4 June 1945, Lynx anchored upon arrival and remained there until 8 June, when she shifted to Moore's Dry Dock Company's Oakland yard.

Derangement to her anchor windlass prevented the tug Point Arena, with her tows, section 52 of ABSD-7 and YF-1012, from getting underway with the convoy as it put to sea, bound for the Marshall Islands.

On the afternoon of 28 July, Lynx transferred Lt. Wuestenfeld, her medical officer, to Hillsboro Inlet to treat a sick sailor, but the remainder of the voyage proceeded uneventfully, FE-3 reaching Eniwetok on the morning of 2 August.

3 at the Hurley facility, where she remained moored, undergoing the decommissioning process in the wake of the Office of the Chief of Naval Operations (OpNav) despatch of 26 September, that ordered the vessel's inactivation, through the end of October.

[4] Underway at the start of the forenoon watch on 1 November 1945, Lynx steamed to Suisun Bay, California, where she dropped anchor in anchorage 26, berth E-14, tying up alongside the freighter Charles M. McGroarty at 11:19.

[4] Resuming her original name, Juan Bautista de Anza, the ship remained in reserve until purchased by Union Minerals and Alloys Corporation, for non-transportation use (NTU), on 3 October 1972, for $40,000.00.
