As delivered by MBDA,
the Aster 30 missile – which
can sustain up to 60 “
g”
ma­
noeuvres without breaking
up – has a tandem frst stage
solid propellant booster mo­
tor which is jettisoned after
launch and turn-over, just
before the beginning of the
mid-course phase. The frst
stage booster, developed by
(Fiat) Avio, has a length of
2.3m, weighs 340kg, and has
a burn time of 3.5 seconds;
by which time the missile
has already reached Mach
4.5 (over 5,000km/h) and is
closing on its target. Two stee­
rable nozzles provide the mis­
sile with thrust vector control
during the initial fight stage.
All Aster family of missiles
combines a powerful aero­
dynamic control “PAF” with a
direct force control “PIF” (or
Pilotage en force
), using late­
ral thrusters placed right at
the centre of gravity of the kill
vehicle in order to optimise
the vehicle response time.
The “PIF” operates just before
target intercept (it is a unique
MBDA patent). This innova­
tive control concept provides
the weapon with unequalled
agility and manoeuvrability
within its whole intercept do­
main, especially at high alti­
tude where air density is low.
After jettisoning the frst
stage booster motor, the se­
cond stage of the missile is au­
tomatically ignited. It weighs
110kg for a length of 2.60m
and a diameter of 0.18m and
carries four long rectangular
wings plus four blunt-tip­
ped triangular control fns at
the rear of the body – a true
MBDA signature, M
ica
style.
The missile second stage is
ftted with a solid propellant
sustainer motor. It represents
the Aster 30 spearhead which
uses inertial mid-course gui­
dance, with correction update
propelente sólido. Ele repre­
senta a liderança do Aster 30
que utiliza orientação inercial
de meio curso, com dados de
atualização transmitidos em
tempo real a partir do centro
de controle de tiro em terra
através do uplink do canal de
dados do radar multifunção
Thales Arabel do MRI. O As­
ter 30 torna-se, assim, escra­
vizado ao curso do alvo que
se aproxima, mesmo que este
começe violentas manobras
evasivas. Para este objetivo, o
Aster 30 está equipado com
uma unidade de orientação
data being transmitted in real-
time mode from the ground-
based fre control centre via
the MRI's (the Thales Arabel)
multi­function radar) uplink
data channel. The Aster 30 be­
comes thus slaved to the in­
coming target's course even
if this last starts violent eva­
sive manoeuvres. To this aim
the Aster 30 is equipped with
a Sagem Agyle inertial gui­
dance unit (linked to a Sistemi
Inersiali guidance reference
system) installed precisely on
its centre of gravity, thus ob­
viating unbalanced heavy
“g”
loads on the missile structure
– since unlike other known
interception missile, the Aster
30 does not roll in the fnal
phase of fight but rather skids
sideways. This in using the PIF
guidance control system to
exhaust gases through one or
two nozzles, therefore gene­
rating a controlled sideways
thrust pulling up to a stun­
ning 60
g
acceleration!
As the Aster 30 approaches
the target in the terminal
phase on a reciprocal fight
path, the missile uses an ac­
tive pulse Doppler radar see­
