Meson Bomb
From FreeSpace Wiki
The Meson Bomb is an experimental demolition warhead developed at the Hideki Institute in Vega. First devised as a large scale demolition bomb to destroy meteor and asteroid fields, it was first deployed to destroy the Knossos subspace portal in Gamma Draconis to prevent the Shivans from invading Capella. Up to 17 Meson bombs have been produced so far; three were used to destroy the Knossos subspace portal in Gamma Draconis and 14 more were retrofitted in decommissioned destroyers, GTD Bastion and GTD Nereid to collapse the nodes to Vega and Epsilon Pegasi.
The Hideki Institute was named after Hideki Yukawa, a leading Japanese theoretical physicist.
