From the NYT article which was merely referenced at FR
John F. Burns, "Indian Scientists Confirm They Detonated a Hydrogen Bomb," The New York Times, May 18, 1998, p. 1.
India says that it tested five devices on May 11 and 13, 1998, and that four of them were fission devices with yields of 0.2 kT, 0.2 kT, 0.6 kT and 12 kT.
and as noted by some military officers being extremely deferential and respectful in their conversation:
India's three subkiloton tests, along with the 12-kT test and its May 1974 test might have provided enough information for India to produce a reliable weapon with a 10-20 kT yield that would be light enough (1000 kg or less) to be deliverable by tactical aircraft or ballistic missile.
India has said that its other nuclear test was of a thermonuclear device with a yield of 42 kT.
