Sight
MiC (missile in container)
What is the role of the end caps
Provide protection for the launch tube
Speed of the missile in the tube?
50 m/sec
What guidance and initiating devices does Bolide have?
Beam riding missile with extended range to older variants and has adaptable proximity and impact fuze
What is the NEQ of Bolide?
5.34kg
What does MiC stand for?
Missile in Container
What is the NEQ of Bolide? Including Propellant
5.34kg
What is the launch motor burn time of the Bolide?
Approximately 40m/s
In the Bolide, what components does the EP2 contain and what function do they perform?
LP2 contains the thermal battery, voltage converters and stabilisers used to produce the missile electrical power
What is the launch motor burn time of the Bolide?
Approximately 40m/s with burnout occurring within the launch tube
Describe the shape and dispersive effects of the casing of the warhead on the Bolide?
The casing has a convex contour to provide an effective dispersion of fragments both forwards and rearwards
What additional layers are used in the warhead and what is contained in that layer which enhances frag effect for the Bolide?
A plastic layer around the steel casing containing approximately 3000 tungsten spheres to enhance frag

RBS70 Operation
- Upon firing button pressed: • The thermal battery initiated 0.2 --.05 sec • Missile gyro initiated • Missile electronics begin • Nozzle spoiler activation • Release of missile lock • Ignition of launch motor • Leads ripped off missile (EP1 interface) • After 5mm movement shackle unit released • Recoil motors ignite (reducing recoil) • Missile leaves launch tube • Wings unfold and lock into position • Two wing switches close circuit • Ignition impulse to ignite Sustainer motor • Sustainer motor fires • 7 G’s acceleration closes SAD circuit • SAD stepper motor aligns firing train • EP3 detector tracks transmitter beam • EP1 analyses transmitter strength and provides course corrections to the rudders through the rudder mechanism • Missile closes with target • Detection and functioning • as per PROX mode Functioning • Off, Normal, Small Target
