The Heavy Autocannon/15 was developed by Clan Ghost Bear somewhere around 3060. It is essentially an autocannon/10 with a stronger barrel firing shells with a stronger propellant. This allows it to do more damage than a normal autocannon, while keeping similiar range. Unfortunately, it tends to suffer from jams when fired repeatedly, and the shells are also more volatile due to the stronger propellants used.
