RAF to upgrade Chinook fleet to HC4

The RAF are planning to upgrade their entire Chinook CH-47 fleet to a new HC4 standard, this includes the 40 HC2/2As and the "infamous" 8 HC3s which have spent years in storage. The HC4 version will new glass cockpits with HUD and night vision, radio upgrades for compatibility with the Army's Bowman communication system and improved defensive aids. Sounds good, they just need to get the funding for it.
