The village had been cut off from rest of the district due to the floods.
As soon as a message about need to evacaute two women who were in critical condition and 'about to deliver' was received at 4.30 pm, a Chetak helicopter was sent from Jamnagar, said Defence spokesperson Abhishek Matiman in a release.
While the helicopter was on its way, district officials informed that one of the women had already delivered twins and needed to be airlifted immediately.
The helicopter then returned to Nana Matra, this time picking up the other pregnant woman who was bleeding profusely. She was flown across the river where a medical team was waiting with an ambulance, it said.
Incessant rains have been lashing Gujarat for the last two days.
