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™ 1 was a monocular Helmet Mounted Sight from the early 90’s. The Viper 1 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.
