R4-F5 was a R4 astromech droid that helped Jedi Master Plo Koon operate his Delta-7 Aethersprite-class light interceptor. This droid shared the same colors as the starfighter—blue and white. Captain Jag received a coded transmission ordering him to execute his Jedi commander. He and his squad of Clone pilots fired upon Plo's Delta-7, killing the ill-prepared Master. R4-F5 was destroyed when the badly damaged starfighter collided with a clone staging area on a Cato Neimoidian bridge city.
