The Sikoht is a semi-active radar guidance air-to-air missile designed by de Havilland Australia to arm airships. It is capable of speeds of up to Mach 3 beyond the stratosphere with a range of 15km, a deadly addition to any airship. The Sikoht is armed with a 150kg shaped charge designed to throw enormous amounts of scrap metal at a 60-degree cone in front of itself. Its appearance has shifted the balance of power away from battlefleet airships armed with high-calibre cannon.
