India's 55-kiloton nuclear device (referenced)

A referenced Indian nuclear weapon cited in-dialogue with an approximate yield of 55 kilotons. In the episode the device functions as an authoritative strategic threat whose destructive capacity and fragile command-and-control precipitate urgent policy decisions by Bartlet and senior staff. The source material alternately frames it as a thermonuclear/H-bomb and provides a 55 kt figure; the in-text technical classification is therefore ambiguous, so the canonical description emphasizes the cited yield and narrative role rather than a firm technical label.
