Kamikaze is a word of Japanese origin that translates to "Divine Wind". The kamikaze became famous in World War II, where Allied forces used the term to refer to Japanese pilots who made suicide runs, flying planes loaded with explosives into Allied ships. It is sometimes employed by starships, usually as an attack of desperation.
A Jem'Hadar kamikaze attack in the first Battle of Chin'toka (2374)
In 2370, a Jem'Hadar attack ship collided with the USS Odyssey's deflector dish, causing its destruction. Despite the fact that the Odyssey was withdrawing from the battle, the Jem'Hadar made the suicide run to prove to the Federation how far they are willing to go to prevent others from interfering with the Dominion. (DS9: "The Jem'Hadar")
In 2373, at the Battle of Sector 001, Lieutenant Commander Worf intended to ram the USS Defiant into the Borg cube after taking severe damage. The timely arrival of the USS Enterprise-E prevented him from doing so. (Star Trek: First Contact)
In 2374, during the first Battle of Chin'toka, the severely outnumbered Jem'Hadar defenders employed kamikaze attacks against invading Klingon forces, destroying or crippling fifteen ships. (DS9: "Tears of the Prophets")
Also in 2374, in an alternate timeline, the USS Voyager performed a kamikaze move against the Krenim weapon ship, causing the destruction of both vessels. Due to the destruction of the temporal core, the ship and all associated events were erased from history. (VOY: "Year of Hell, Part II")
In 2379, during the Battle of the Bassen Rift, Captain Picard ordered the USS Enterprise-E into a collision course with Shinzon's Scimitar after conventional weapons were exhausted. Once the vessels were entangled, he intended to destroy both with the Enterprise's autodestruct. However, the autodestruct system was offline and the Scimitar was able to pull itself free.
