Isolytic burst

An isolytic burst was a ship-mounted subspace weapon, outlawed by the Second Khitomer Accords, utilized by the Son'a in the 24th century.

In 2375, a Son'a battle cruiser detonated an isolytic burst during the Son'a's attempt to prevent the USS Enterprise (NCC-1701-E) from leaving the Briar Patch. The burst caused a subspace tear to form, which was attracted to the Enterprise's warp core. The tear was sealed when Commander La Forge ejected the core and detonated it, neutralizing the cascade.
