| 1943 | May 7 | Keel laid down by the Portsmouth Naval Shipyard, Kittery, ME. |
| | Sep 15 | Launched. |
| 1944 | Jan 1 | Commissioned with LCDR. Bernard A. Clarey in command.
|
| | Feb 17 | Pintado departed Portsmouth, NH. for torpedo trials at Newport, RI., training out of New London, CT. and antisubmarine warfare tactics and experiments with torpedo developments out of Key West, FL. |
| | Mar 31 | Pintado sailed for the Pacific. Transited the Panama Canal. |
| | Apr 23 | Pintado arrived at Pearl Harbor, HI. |
| | May 16 | On her 1st war patrol, Pintado served as flagship of a wolfpack, commanded by Captain Leon P. Blair, which also included the submarines Shark (SS-314) and Pilotfish (SS-386). The attack group departed Pearl Harbor, HI. |
| | May 20 | The group touched at Midway Island 20 May – 21 May, and headed for waters West of the Marianas and South of Formosa. |
| | May 31 | They formed a scouting line in search of a convoy reported by submarine Silversides (SS-236). After sparring with the convoy’s escorts through the night, Pintado managed to reach attack position shortly before dawn.
|
| | Jun 1 | Pintado fired a spread of 6 torpedoes at overlapping targets, destroying the 4,716 ton cargo ship Toho Maru. She then daringly came within 700 yards of an escort while bringing her stern tubes to bear on another merchant ship. |
| | Jun 4 | Pintado spotted smoke from a Japanese convoy heading toward Saipan. She and her sister subs headed for the enemy, and soon Shark sank the 6,886 ton cargo ship Katsunkawa Maru before slipping away from a heavy depth charge attack. |
| | Jun 5 | The American submarines continued to shadow the convoy and Shark’s torpedoes accounted for 2 more cargo ships.
|
| | Jun 6 | Pintado made kills with a spread of torpedoes at overlapping targets. An awesome explosion tore one ship apart, her bow and stern both projecting up in the air as she sank. The stern of a 2nd was under water before she was swallowed by smoke and flame. |
| | Jun 6 | (Cont'd.) These victims were later identified as the 5,652 ton Havre Maru and the 2,825 ton Kashimasan Maru. A plane and five escorts tried to box in Pintado and dropped over 50 depth charges, but she escaped damage.
|
| | Jul 1 | Pintado then headed for the Marshall Islands, arriving Majuro for refit.
|
| | Jul 15 | Pintado's 2nd war patrol took her to the East China Sea. (Exact date unknown) |
| | Aug 6 | Pimado sank the 5,401 ton cargoship Shonan Maru and damaged another target in a Formosa-bound convoy, before scampering away through a downpour of exploding depth charges. |
| | Aug 22 | Pintado spotted an 11 ship convoy guarded by 3 escorts. After dark she moved into the center of the convoy, passing a scant 75 yards from an escort, to attack the Tonan Maru No. 2., a former whale factory. |
| | Aug 22 | (Cont'd.) 2 spreads of torpedoes from Pintado left the monster ablaze and sinking and damaged 2 other tankers. Tonan Maru was one of the largest merchant ships sunk by an American submarine during World War II. |
| | Aug 22 | (Cont'd.) which LCDR. Clarey, as XO of Amberjack (SS-219), had helped to sink in Kavieng Harbor, Bismarck Archipelago, 10 October 1942. The Japanese had raised the ship and towed her to Japan where she was repaired and converted to a tanker. |
| | Sep 14 | Pintado arrived at Pearl Harbor, HI. |
| | Oct 9 | On Pintado’s 3rd war patrol, LCDR. Clarey commanded a wolfpack which included Atule (SS-403) and Jallao (SS-368). The group departed Pearl Harbor, HI. heading for the South China Sea. |
| | Nov 3 | Pintado’s periscope revealed “the largest enemy ship we have ever seen”, an oiler in the support group for the carriers. Clarey fired 6 torpedoes at the target, but the enemy destroyer Akikaze crossed their path before they could reach their target. |
| | Nov 3 | (Cont'd.) The destroyer disintegrated in a tremendous explosion which provided an effective smoke screen protecting the original target until the 2 remaining Japanese escorts forced the submarine to dive and withdraw to escape exploding depth charges.
|
| | Nov 14 | Pintado joined Halibut (SS-232) on and escorted the damaged submarine to Saipan, Marianas Island. |
| | Nov 19 | Pintado and Halibut arrived at Saipan, Marianas Island. |

| | Dec 12 | On the night of 12 December – 13 December, Pintado sank two enemy landing craft, the Transport No. 12 and Transport No. 104, and claimed she had sunk a third, the Transport No. 106, but apparently missed. |

| | Jan 27 | Pintado departed Brisbane, Australia on her 4th war patrol, but found no targets as she patrolled the Singapore-Saigon shipping lanes. |
| | Mar 30 | Pintado ended her patrol at Fremantle, Australia. |
| | Jun 1 | Pintado sailed to Pearl Harbor, HI. before getting underway for her 5th war patrol on lifeguard station for bomber raids on Tokyo. |
| | Jun 26 | Just south of Honshu, a smoking B-29 bomber crossed Pintado's bow at about 2,000 feet, dropped a dozen parachutes, and exploded. In less than an hour Pintado had rescued the entire crew which she took to Guam, arriving Apra Harbor a fortnight later. |
