So... The Dutch LCFs have entered a refit. Amongst others, they have recieved new diesel engines, their diesel exhausts have been modified to prevent fumes wafting over the flight deck, and extra satcoms have been installed. SIRIUS has been installed at some point in the past.
Also, there are differences between the port and starboard views of the ships.
First to recieve the refit, the Tromp.
