Daniel Bedemi, Sushil Singh and Babatunde John scored for the winners while ONGC pulled back through Jagdish Modi and A. Naresh.
The Sikkim club, owned by Bhaichung Bhutia, began on a strong note finding their mark in the very third minute through Daniel Bedemi.
Much against the run of play, ONGC restored parity in the 17th minute when Jagdish Modi latched on to a loose ball and volleyed home.
Stung by the reverse, USFC went ahead within three minutes from a counter-attack with Sushil Kumar heading into the cross-piece but Babatunde was alert enough to tap in the rebound. Sushil later made amends for the earlier miss making it 3-1 for his team.
ONGC went all out in the attack and Naresh converted from the spot in the 90th minute. The penalty was awarded after Kenistan was brought down inside the box.
A Spectator's View Of The Match Between USFC And ONGC
USFC Coach Stanley Rozario said his team needs some time to reach their peak, while stating his team was unlucky not to make it to the top flight earlier this year.
“The quality in our side is unmatched. We were unlucky to not qualify for the I-League. But this time our side is even better,” said Rozario.
In Friday's other Group B match played at the Howrah Stadium, Royal Wahingdoh also made a winning start by defeating Southern Samity by a solitary goal.
Bhoy Singh scored the winner in the 45th minute, while Samity failed to cash in on their home advantage.
United Sikkim's next assignment is against Royal Wahingdoh on Sunday, while ONGC lock horns with Southern Samity on the same day.
Come Saturday, Ar-Hima is scheduled to play Vasco SC at the Howrah Stadium at 2.45 pm (IST).
