405 In
Service
A Vistar 405 system (IM405) was fitted to a US Delta force patrol boat
in 1988. This led to a further five systems for US Navy Seals
patrol craft in 1990. These were fitted with Thorn LITE thermal imagers
and 135mm Vistar Vega Image intensifiers.
Seven Vistar 405 systems (MEOSS) were fitted to HM Customs cutters in
1993. These were fitted with Marconi TIVS thermal imagers and 135mm
Vistar Vega Image intensifiers. Vistar has an ongoing contract
servicing these systems. Five were
re-ftted with new thermal imagers and daylight cameras in 2003.
Two Vistar 405 systems (IM405/1) were installed on the Storbaelt
Bridge in
1993. These were fitted with 18mm image intensifiers and daylight
cameras. Three more were fitted in 1994, this time using Marconi TIVS
thermal imagers and daylight cameras. The tracking heads and sensor
housings are internally heated allowing the 405 to function in the
extreme cold.

HMCC Sentinel. The largest of seven UK Customs patrol craft
originally fitted with MEOSS systems. Six of these craft are
being decomissioned and replaced with four new vessels. The Vistar
systems have been upgraded and transferred. Sentinel is not one of
them. She remains in service for the time being.
