The Jettison Fitting Kit (JFK) is a Special to Role equipment Common Interface System for Medium Weight Tracked Combat Vehicles that provides rapid hydraulic connection and release.


The JFK allows the rapid interchange and attachment of a wide range of Pearson Engineering Special to Role equipment, as well as fast release in an emergency using an integral hydraulic system.


The JFK comprises an upper pin and two lower clevis attachments.  No special adjustments are needed to secure the attached equipment once it is in place and the system requires minimal personnel to both fit and operate.


An on-board hydraulic and control system may be supplied as part of the JFK that provides power and control to the Special to Role equipment.

Operation and Control

The JFK lock/jettison function is provided by an upper hydraulic cylinder.  A manually operated back-up system is provided in case of failure of the primary system.  Lanyard operated quick release hydraulic and electrical couplings are provided for power and control connection to the Special to Role equipment.



If required, on-board power and control is provided by a Mission Equipment Control Unit (MECU) mounted conveniently for the driver; a Mission Equipment Signal Unit (MESU) that acts as a main hub for all power and control functions and where the associated control software resides; and a Valve Pack Unit (VPU) that contains the hydraulic control valves.


If required, a Hydraulic Power Pack (HPP) provides hydraulic oil independently from the vehicle hydraulic system in order to operate the JFK and Special to Role equipment.
