At its peak, the former Soviet Union had the world's largest biological warfare program, with somewhere between 25,000 and 32,000 people employed in a network of 20 to 30 military and civilian laboratories and research institutions. Biological agents were developed and stockpiled for delivery by a variety of means, including long-range missiles. Special cooling systems in the warheads protect the biological agents during re-entry.
Parachutes slow the warhead, whcih at a set altitude dispense over a hundred small bomblets.
