Title: Viper I HMD
Dwg No: 229-061682
Ser No: 0001
In 1992 the Viper™ family of HMD’s was commenced comprising a range of visor projected systems from the Monocular Viper™ I, to the Binocular Viper™ II. The family of helmet systems has now been renamed Striker®.
Viper™ I was a monocular Helmet Mounted Sight from the early 90’s. The Viper™ I provides 20° circular FOV, with 15-mm exit pupil, and 70-mm eye relief. Excluding the oxygen mask, it weighs 3.8 lbs (1.7 kg). The HMS used a single “half inch” CRT and an optical system which projected onto the visor. The high brightness imagery is reflected to the pilot’s eye from a 70% transmission neutral density coating on the visor and thence to the right eye. This ensures high outside world transmission without colouration. The Viper™ display module can be fitted to all sizes of UK and US flying helmets. The Viper™ I was part of a family of helmet systems which could provide stroke symbology, video from an external source or a combination of both.
The ’Look & Shoot’ Sight was cleared for fast jet flight test and was flown on the X-31 research aircraft and in the F-16 and the EPAF F-16 (Belgium, Denmark, Norway and the Netherlands were known as the European Participating Air Forces (EPAF). Together with the US, they started a unique multi-national development program for the F-16. Under the terms of the agreement, F-16 Fighting Falcons for the EPAF nations were to be produced locally.
The weight includes the 3.2m cable.
