(Armed forces HKP.4A)
The HKP.4B was born from the original HKP.4A, redesigning the original into a ASW system. While it is often mistaken for the Boeing CH-47 “Chinook,” it is actually a Boeing CH-46 “Sea Knight” also known as “Boeing Vertol-107-II.” This was given a specialized radar in the nose for search and tracking of sea targets, this was to guide the Torped 45 semi/active homing Torpedo system from Saab. While this was its most advanced weapon, it wasn’t its only. Also being mounted with 3 anti-submarine depth charges under the name of Sjunkbomb 51, with a literal translation of “Sinking bomb.”
