"Stronger than Demolition Ship. Filled with explosives. Self-destructs when used."—Age of Empires II description
The Heavy Demolition Ship is a naval vessel in Age of Empires II that can be trained at the Dock once the Imperial Age is reached. It is packed with explosives that blows up enemy ships, Docks, land units caught in shallows, and anything too close the shore. It has better armor (although still very little) and a much stronger and larger explosion than its predecessor. Since they are suicide units, they may be referred to as the Petards of the sea.
The * indicates that the civilization can fully upgrade their Heavy Demolition Ships, i.e. gets Dry Dock. Faith and Heresy are not taken into account because they only contribute to their combat strength in a very situational manner.
Heavy Demolition Ships are very good against other ships, especially Fire Ships and fully loaded Transports. Heavy Demolition Ships explode when killed, dealing blast damage to any nearby units. However, they do not cause friendly fire damage, so any nearby allied units will not be damaged.
Like its predecessor the Demolition Ship, its tactics resemble those of a cruise missile. The Heavy Demolition Ship and its predecessor are the fastest military vessel in the game (especially with Dry Dock researched), much faster than most naval units, making it capable of chasing down enemies. It can cause great damage when it hits and will destroy most ships in one shot, but since it is a suicide unit it may not be worth the resource cost. It all depends on the exact situation. Heavy Demolition Ships are useful against the Galley line if they manage to approach to them, excellent against Fire Ships, and devastating against Transport Ships. They do worse against the heavily armed and armored Turtle Ship. However, in sufficient numbers (3 to 1), they can be the only effective way to destroy them quickly in the water. Longboats are a severe threat to Heavy Demolition Ships.
Heavy Demolition Ships can also be an excellent tool for dealing with the enemy shoreline infrastructure as they can rapidly take down enemy Docks without having to compromise other naval vessels intended to survive that can support Heavy Demolition Ships by distance.

"Demolition ships eventually were made larger and filled them with explosives of greater power, especially gunpowder. This heavy demolition ship resulted in greater explosions and a greater chance of damaging or destroying one or more enemy ships. It could be devastating against a large target or many enemy ships caught traveling close together."
