The Slave 1 is a highly modified Kuat Systems Engineering Firespray-class patrol and attack craft. It was used originally for Republic law enforcement before it came into possession of Jango Fett, who outfitted it with weapons of all sorts. His son/unaltered clone, Boba Fett, inherited the Slave 1 from his father Jango. Since then the ship has been improved and customized for the needs of the most feared bounty hunter in the galaxy.
The most famous scene with Jango in the pilot seat was the dogfight with Obi-Wan’s Jedi Starfighter (delta-7 aether-sprite class light interceptor) in the asteroid field over Geonosis. Jango exhausted every resource in his grasp to capture Obi-Wan: first lasers, then charges, and finally a heat-seeking missile.
The most famous bounty Boba achieved with the Slave 1 was tracking and capturing the Millennium Falcon, and bringing Han Solo to Cloud City (Bespin). Possibly the most iconic scene in The Empire Strikes Back was the carbon-freeze chamber, where Han got frozen into a block of carbonite. (I couldn’t get a proper picture of that scene, so I chose this one instead).
Here are the weapons that brought this ship to victory so many times.
Laser cannons: the Slave 1 has two rotating twin laser cannons on the end of the nose. Interestingly, although it’s a fact that they are laser cannons, they were never fired in the films or the Clone Wars TV series.
Proton torpedoes: the Slave 1 has two torpedo launchers on the very tip of the nose (a concealed turret). Proton torpedoes are heavier firepower than standard laser cannons.
Tractor beam: tractor beams pull in ships or floating objects. Boba’s ship has one on the bottom of the nose, right under the lasers and torpedoes.
Ion cannons: Boba replaced the hidden laser cannons seen in the very first picture with hidden ion cannons simply for weapons diversity. Ion cannons shoot highly charged plasma to disable enemy ships without destroying them. He replaced it at about the time he painted it red and green, (before that it was blue and gray).
Heat-seeking missile: heat-seekers are a type of homing missile that follows enemy ships and detonates on impact. The Slave 1 has two of them.
Seismic charges: seen in Attack of the Clones, Jango used seismic charge to detonate Obi-Wan’s ship in Geonosis’s asteroid field. Had the bright blue shockwave hit the ship, it would have sliced it cleanly in half, as demonstrated by several asteroids it hit.
