                                                     successfully carried out.
     During the year, twin-screw continuous
mixer and other sub-systems of capacity 50-80
kg/h for development of composite propellants
in continuous-mixing system were realized.

• Dynamic Trials of Modified 120 mm FSAPDS              placed an indent for 124 MBT Arjun tanks
                                                        on Heavy Vehicles Factory (HVF), Avadi.
   Mk-II (Improved) Ammunition: The 120 mm              Till date, 80 out of 108 tanks have been
   FSAPDS Mk-II ammunition with a few design            successfully operationalised and procurement
   modifications was evaluated in respect of            action completed for nearly 45% of the Indent.
   general functioning, safety, lethality on a
   number of occasions at this range. Consistency
   performance was satisfactory. No penetrator
   breakage during the firing was observed.
   Penetration trial was conducted against 230
   mm RHA plate inclined with different Angles
   of Attack (AoA). Penetration capability of
   575 mm Depth of Penetration (DoP) against
   RHA was observed. Results of Users’ trials
   have been highly encouraging.

• User Trials of 125 mm FSAPDS Practice Ammunition:

   ARDE is developing 125 mm FSAPDS practice
   ammunition for T-72/T-90 Tanks. It is a two-
   piece ammunition fired through 125 mm
   smooth-bore gun. The ammunition is required
   for training of crew. User trials including
   safety and functioning of ammunition, EFC,
   consistency within 0.40 mils and accuracy
   were successfully carried out.

• Dynamic Trials of 125 mm FSAPDS (500 DoP)

   Ammunition: ARDE is developing 125 mm
   FSAPDS Mk-II ammunition having 500 mm
   DoP for T-72 Tank. It is two-piece ammunition
   fired through 125 mm smooth-bore gun. After
   finalising the design, pilot lot of Qty 200
