The Luch state design bureau in Ukraine is developing a
2.75-inch 'smart' rocket for Singapore, writes Michal Zdobinsky. It
will negotiate the transfer of technology and manufacturing rights
for the homing and steering module to Singapore, allowing local
companies to manufacture the module and convert existing 2.75-inch
unguided rockets that can be used to arm Singapore's
helicopters.
The upgrade uses technology derived from a Ukrainian programme to
develop a guidance and control module to convert the 80 mm AP-8
unguided air-to-surface rocket into a 'smart' AP-8L guided round.
The AP-8 is an improved Ukrainian derivative of the Russian S-8
unguided rocket.
The Ukrainian programme to develop the AP-8L was initiated by the
Ukrainian Ministry of Defence, and work started at Luch at the end
of 2004. The modified missile has a new front section, containing a
laser seeker and a steering unit with two flip-out aerodynamic
control surfaces. It retains the rocket motor of the standard AP-8
rocket. The laser seeker of the AP-8L is adapted from an existing
weapon, JMR was told, but this weapon was not identified.
Installation of the new front section increases the length of the
rocket from the original 1,586 mm to a total of 1,725 mm. To
partially compensate for the new hardware, the warhead was trimmed
in weight from 4.7 kg to 4.3 kg. Despite this measure, the AP-8L
weighs 14.7 kg, 2 kg more than the unguided rocket.
Like the AP-8, the AP-8L can carry either a high-explosive (HE) or
a shaped-charge (HEAT) warhead. Although the latter is lighter than
the original pattern carried by the unguided rocket, the
performance of the shaped charge was enhanced to preserve its
armour-piercing capability, matching the older warhead's ability to
penetrate 400 mm of homogenous steel armour.
AP-8L rounds can be launched from the standard 20-tube B-8M-1
rocket pods, or from the similar B-8V-20A pods intended for
helicopter use. They can be carried by aircraft such as the Su-17,
Su-22, Su-25 or the MiG-27K, which carry the Klyon-PS laser
rangefinder/designator. Other types of aircraft or helicopters
would have to be fitted with suitable laser target
designators.
According to the Luch design bureau, all the main components of the
AP-8L are tested and proven, but at the IDEF 2005 defence show held
in Ankara, Turkey, in September 2005, the bureau indicated that
live firing tests of the complete missile had yet to begin.
Until these have been conducted, neither the declared effective
range of the new weapon, given as 1,200-5,000 m, nor the claimed
70-80 per cent hit probability against a tank or armoured personnel
carrier target can be fully proven.
In parallel with the AP-8L programme, Luch is working on the
upgrade scheme for the 2.75-inch rocket, a project being financed
by Singapore. According to the deputy director general of the Luch
design bureau, Georgiy S Petrov, Singapore would be able to use
virtually any laser designator, with only a minor modification to
the radiating frequency being required to match the new weapon.
Petrov believes that the development and testing of the guided
2.75-inch rocket will be completed by the end of 2006.
