India’s growing military industrial complex has begun to seriously look
towards international markets which could be quite considerable for
Indian defence wares if properly cultivated. To that end, the Defence
Research and Development Organization (DRDO) has decided to feature a
range of indigenously developed armaments along with its production
partners at the ‘International Aerospace and Defence Exhibition
(ADEX-2013) scheduled to be held at KINTEX, Seoul, South Korea from 29
Oct – 3 Nov 2013′, which has participants from more than 30 countries.
Apart from the choice of venue itself for DRDO’s big international
coming out party what else is rather interesting is of course the kind
of hardware which it will put on display at Seoul. Particularly striking
will be the Pragati surface to surface missile (SSM) which is being
exhibited for the first time abroad or anywhere for that in this avatar.
Pragati is an export variant of the Prahar tactical battlefield support
missile which was tested in July 2011 and is meant for the Indian
Army’s artillery arm.
The system that will be exhibited at Seoul broadly has the same specs
as the Prahar though it is being advertised abroad with slightly
different ranges than what has been reported domestically for the Prahar
(see the specs sheet given below). Importantly, Pragati like Prahar
also depends on an indigenous ring laser gyro based inertial navigation
system that can receive GPS updates to remove accumulated errors.
Now the market for such tactical battlefield missiles has been
expanding in recent times as armies around the world want to possess
rocket artillery that would allow them to engage communication and
ammunition nodes in the rear. The Chinese and Israelis have been early
movers in this market and have exhibited long ranged precision guided
systems of this variety in the past few years. The United States has of
course sold the ATACMS to its allies here and there. Be that as it may,
the fact that a usually conservative MEA has approved the exhibition of
offensive weapons overseas for potential sales in a much more concerted
manner is indicative of a welcome shift in the Indian mindset. Needless
to say, defence exports can help India defray the costs of development
and serve as a major tool for diplomacy
.
Coming back to the Pragati, if India is able to bring down production
costs for this system a large market could exist for it amongst ASEAN
and African countries. Now, the Prahar/Pragati configuration shares its
missile frame and some avionics with the Advanced Air Defence (AAD)
interceptor from DRDO’s ballistic missile defence program. So both the
AAD and Prahar/Pragati could actually be produced in tandem facilitating
greater economies of scale thereby bringing down costs associated with
both sets of systems.
In a manner of speaking, a part of the total R&D costs of the
Pragati has in any case been amortized by those expended on developing
the basic airframe of the AAD interceptor. Apart from the Pragati the
following systems have also made it to Seoul as DRDO delineates in the
following release:
AKASH (Surface to Air Missile System) Akash is a
medium range surface to air missile system which provides area air

CTD Logger CTD Logger is a state-of-the-art sensor
for measuring the three important oceanographic parameters – salinity,
temperature and depth. These parameters form the regional description of
ocean. Salinity is determined through conductivity measurement, and
depth through pressure measurement. Speed of sound in ocean depends to a
large extent on salinity, temperature and depth, thereby necessitating
the accurate profiling of these parameters for sound profiling and
characterization. As the conventional surveillance systems onboard ships
and submarines use the acoustic method of detection and ranging, CTD
logger finds immense applications for use in maritime or homeland port
security, apart from its use in ocean research. So apart from some key
munitions being developed by DRDO that are either already in service
with the Indian military or will certainly see service with the Indian
military (i.e Astra, Prahar) we also find a host of sensor equipment on
display- an area that has emerged as a domestic strength. Of course, the
LCA family will also be showcased and I leave you with this video of
the LCA during the test phase. Watch out for the laser guided bomb
release at round 00:24 seconds.
