Within an hour, however, the convoy was safely into Cam Ranh Bay. ''Seadragon'' retired eastward. After dark while on the surface, recharging, she sighted a destroyer and attempted to slip away undetected. The destroyer spotlighted her.

for a final check, she was spotted from the air. Three salvos of bombs dropped close aboard, but ''Seadragon'' went deep and again made her way eastward—this time to investigate the cause of the plane sightings. She surfaced after 18:00. No oil or air leaks were spotted, but her black paint was coming off the entire hull. Red lead undercoating showed from the waterline to the side plating, and, "in spots", on the bow planes and propeller guards. In shallow tropical waters, her original black paint was easily spotted against a light colored background. With red showing, she stood out regardless of the color of the seabed. From then on, ''Seadragon'' ran at between periscope exposures except in areas known to be patrolled by air, when she went to . On 14 January, she patrolled in the Cape Varella area. On 15 January, she shifted southward, and, on 16 January, she stood off Hon Lon to wait for a convoy. At 11:15, after a periscope observation, she was again spotted and bombed from the air. She returned to Cape Varella where the depth of the water permitted a closer patrol to the shore line. During the next six days, she sighted several targets but had no luck with her torpedoes. Early on 23 January, she sighted a four-ship convoy which she stalked until daylight, then attacked. At 08:06, she fired at the lead ship and scored with a hit on the port quarter. She then fired two at the ship and missed. The third and fourth ships ran off to the southeast and west respectively. The second ship moved in toward the first; then, listing to port and down by the stern accompanied it as it ran for the beach. ''Seadragon'' surfaced and went after the third ship, but the appearance of an enemy plane forced her to break off the attack. The submarine remained off the Indochina coast for another four days, then set a course back to

Twenty-nine seconds later the first torpedo exploded halfway to the target. The second broached and circled abeam of the target. The destroyer avoided the third. ''Seadragon'' changed course and went to to avoid the circular and the expected depth charging. None of the depth charges were close, but a second destroyer soon joined the first, spotted the submarine as she came up for a periscope observation, and turned on her.

The torpedo missed ahead, all three ships changed course toward ''Seadragon'' with the leader proceeding down the torpedo track firing her bow gun. Depth charges were dropped indiscriminately. Ten minutes later, the three had turned toward shore. ''Seadragon'' then shifted southward to intercept enemy traffic off Hon Lon Light. A few hours later, she sighted two freighters and fired tubes 1 and 2 at the lead ship. Her No. 1 tube did not fire, and her No. 2 torpedo missed astern. Two more torpedoes were fired at the ships, but both missed. Enemy planes arrived on the scene soon afterward and for over two hours aerial depth charges in salvos of two and three were dropped. Despite water depth of , submarines were visible at any depth against the light colored bottom. ''Seadragon'' survived the close bombing and continued her patrol. During the next week, she attempted to close several ships, but was unable to attain attack positions. On the night of 11 July, her losing streak ended. Just prior to midnight, she sighted smoke and opened out to the westward to overtake the target. At 01:56 on 12 July, she began her approach; and, 14 minutes later, she launched three torpedoes. Two hit, but the third missed astern. A merchantman, ''Hiyama Maru'', began settling. By 02:19, she had been abandoned. ''Seadragon'' submerged and resumed her patrol eight miles (14.8 km) northeast of Cape Varella. On the morning of 13 July, ''Seadragon'' torpedoed and sank her second victim of the patrol. ''Shinyo Maru'' was hit approximately abaft the beam and settled immediately. ''Seadragon'' moved out of the area and hunted along the Haina Varella routes for a few days. On 16 July, she was back off Cape Varella; and, soon after 10:30, she fired on a four-ship convoy. Five minutes later, the torpedoes exploded on the beach. The four ships turned toward ''Seadragon'' and commenced firing their guns. ''Seadragon'' fired two more torpedoes and went deep. A few minutes later, she came to periscope depth. Only three ships remained on the surface. ''Hakodate Maru'' had been sunk. On 20 July, ''Seadragon'' departed the South China Sea and made her way south to Australia.

The second torpedo explosion, however, had damaged ''Seadragon''. The force of the explosion had knocked down the personnel in the forward torpedo room, and the final bow torpedo in No. 1 tube, the outer door of which was open, was forced against the tail buffer. The countermining effect forced the torpedo forward shearing off the guide stud and tripping the starting lever. The outer door could not be closed. Depth control was lost. The final bow torpedo was fired. Control was regained as the torpedo exploded on ''Seadragons port quarter at an estimated 200 yards.

On her eighth war patrol, 24 September to 5 November, ''Seadragon'' again returned to the Marshall Islands and spent 31 days hunting in the sea lanes to Kwajalein. Again Japanese antisubmarine measures hindered hunting; and, of the five ship contacts made, only two could be developed and only one attack was made. On 13 October, she damaged an enemy transport.

She closed the convoy; fired on the third ship, the heaviest laden; then went deep and rigged for depth charging. The patrol boats moved toward ''Seadragon'' as ''Daiju Maru'' sank and, during the next two hours, delivered a 40 depth charge attack. Later that day, the submarine conducted an unsuccessful attack on a naval auxiliary; and, on 26 April, she moved out into the

Eleventh patrol, September – November 1944

Re-engined at Mare Island during the summer, ''Seadragon'' returned to Pearl Harbor on 7 September and departed on her 11th war patrol, a coordinated patrol (" wolfpack") with submarines and , on 23 September. She arrived at Saipan to top off on 3 October. On 4 October, ''Shark'' and ''Blackfish'' continued on to the wolfpack's assigned area in the northern China Sea. ''Seadragon'', delayed by the need for repairs, did not depart until 5 October. On 9 October, she arrived off

. At 06:15 on 24 October, ''Shark'' reported a contact, and ''Seadragon'' headed for the scene. At 07:30, the contact was sighted through the high periscope, but it proved too distant. At 09:20, ''Seadragon'' sighted three enemy merchantmen in a loose column with a

and an airplane as escorts. At 10:55, she launched four torpedoes at the lead freighter. The first torpedo broached and ran erratic, alerting the escort which started for ''Seadragon''. ''Seadragon'' rigged for depth charging. Soon thereafter, two torpedo explosions were heard, and, at 11:01, the first of eight depth charges was dropped. At 11:54, ''Seadragon'' went to periscope depth. The escort was milling around picking up survivors four miles (6 km) astern. The remaining merchant ships were ahead of the submarine and making only two or three knots. As ''Seadragon'' prepared to fire again, the destroyer rejoined the formation. At 11:14, ''Seadragon'' fired four more torpedoes. Three hits were observed. The submarine's second target of the day sank in less than two minutes. ''Seadragon'' went deep. Fifteen depth charges followed. At 13:10, the submarine returned to periscope depth. The deck of the sole remaining freighter was crowded. The freighter was smoking heavily and moving slowly. The escort circled the freighter. At 14:04, ''Seadragon'' fired. The first torpedo tore off the freighter's bow. The rest of the ship went under quickly. At 14:05, the first of 25 depth charges was dropped. Postwar examination of Japanese records identified the sunken ships as the cargo ship, ''Eiko Maru'', and the passenger-cargomen ''Taiten Maru'' and ''Kokuryu Maru''. At 18:58, ''Seadragon'' tried unsuccessfully to raise ''Shark''. She had been sunk after attacking the contact of her 06:15 transmission. On 26 October, ''Seadragon'' headed toward Luzon. On 27 and 28 October, she searched for downed aviators; and, on 29 October, she was ordered to return to Midway.


Twelfth patrol, December 1944 – January 1945

Arriving at her destination on 8 November, she commenced refit; and, on 3 December, she headed west for her 12th war patrol. The patrol took her back into Japanese waters where she hunted enemy shipping and searched for downed aviators into January 1945. On 10 January, she moved into the
