Work on Prithvi was nearing completion when we
entered 1988. For the first time in the country, clustered
Liquid Propellant (LP) rocket engines with programmable
total impulse were going to be used in a missile system to
attain flexibility in payload range combination. Now,
besides the scope and quality of the policy decisions
Sundaram and I were providing to the Prithvi team, the
project’s success depended on creative ideas being
converted into workable products and the quality and
thoroughness of the team members’ contribution. Saraswat
with Y Gyaneshwar and P Venugopalan did a
commendable job in this regard. They instilled in their team
a sense of pride and achievement. The importance of
these rocket engines was not restricted to the Prithvi
project—it was a national achievement. Under their
collective leadership, a large number of engineers and
technicians understood and committed themselves to the
team goals, as well as the specific goals which each one of
them was committed to accomplish personally. Their entire
team worked under a self-evident sort of direction. Working
together with the Ordnance Factory, Kirkee, they also
completely eliminated the import content in the propellant
for these engines.
Leaving the vehicle development in the safe and
efficient hands of Sundaram and Saraswat, I started
looking at the mission’s vulnerable areas. Meticulous
planning had gone into the development of the launch
release mechanism (LRM) for the smooth lift-off of the
missile. The joint development of explosive bolts to hold the
LRM prior to the launch by DRDL and Explosive Research
and Development Laboratory (ERDL) was an excellent
example of multi- work centre coordination.
While flying, drifting into spells of contemplation and
looking down at the landscape below has always been my
favourite preoccupation. It is so beautiful, so harmonious,
so peaceful from a distance that I wonder where all those
boundaries are which separate district from district, state
from state, and country from country. Maybe such a sense
of distance and detachment is required in dealing with all
the activities of our life.
Since the Interim Test Range at Balasore was still at
least a year away from completion, we had set up special
facilities at SHAR for the launch of Prithvi. These included a
launch pad, block house, control consoles and mobile
telemetry stations. I had a happy reunion with my old friend
MR Kurup who was the Director, SHAR Centre by then.
Working with Kurup on the Prithvi launch campaign gave
me great satisfaction. Kurup worked for Prithvi as a team
member, ignoring the boundary lines that divide DRDO and
ISRO, DRDL and SHAR. Kurup used to spend a lot of time
with us at the launch pad. He complemented us with his
experience in range testing and range safety and worked
with great enthusiasm in propellant filling, making the
maiden Prithvi launch campaign a memorable experience.
Prithvi was launched at 11:23 hrs on 25 February 1988.
It was an epoch-making event in the history of rocketry in
the country. Prithvi was not merely a surface-to-surface
missile with a capability of delivering a 1000 kg
conventional warhead to a distance of 150 km with an
accuracy of 50 meter CEP; it was in fact the basic module
for all future guided missiles in the country. It already had
the provision for modification from a long-range surface to
an air missile system, and could also be deployed on a
ship.
The accuracy of a missile is expressed in terms of its
Circular Error Probable (CEP). This measures the radius of
