Vithalbhai Patel, then the speaker of the Central Legislative Assembly of British India, performed her ceremonial ship launching in Glasgow on 14 July 1927.^[5][6] The footage of launching was later presented in documentary film India's Struggle for National Shipping (1947). The ship was completed on 12 August 1927.^{[7][8][9][10][11]}

Mahatma Gandhi had written his concerns in Young India on its launch,

The ceremony ... does not evoke any feeling of national pride or rejoicing. It only serves as a reminder of our fallen state. What is the addition of one little ship to our microscopic fleet? The sadness of the reminder is heightened by the fact that our mercantile fleet may at any moment be turned into a fleet warring against our own liberty or against that of nations with which India has no quarrel...

— Mahatma Gandhi, Young India, 4 August 1927^[5][12][6]

The ship was used to transport cargo between Karachi, Bombay and Colombo. The ship left from Colombo to Bombay in convoy of nine ships (MB-50) in four columns on 9 October 1943. It had 2000 tons of copra and 1800 tons of general cargo. The convoy was escorted by a minesweeper HMIS Carnatic and an armed trawler HMIS Baroda. She had the crew of 74 with three gunners and led by Master James George Connor. She was armed with one 3-inch gun and four machine guns. On 11 October, the weather was fine and it was moving at 8 knots. At 16:30 hours, Jalbala was torpedoed by the German submarine U-532 when she was in station #11 of convoy. It was hit on the port side abreast bridge and second hatch. She sent distress signals and the crew soon abandoned the ship in the lifeboats. After being hit, she started to settle by the head after 10 minutes and sank by the bow after 25 minutes. It sank in the Laccadive Sea west of Cape Comorin (11°40′N 75°19′E / 11.667°N 75.317°E / 11.667; 75.317). HMIS Carnatic dropped depth charges in a counterattack. As she was the only escort, she soon joined the convoy again without picking up survivors due to fear of repeat attack. The master was last to leave the ship but four crew members were lost. The lifeboats with 66 survivors landed on the nearby coast and were taken to Calicut the next day. The chief officer had died two hours before landing of boats. The master had joined six members on a raft which landed later and they were taken to Manglore on 15 October.^{[3][13][4][14]}
