Nordic Co-operation in Mortars
Background and Scope

• Task given 1996 to a Joint Nordic working group
  Study and Develop an armoured mortar system well
  suited for Nordic conditions.
• Joint Nordic 4-Nation Project Agreement signed
  October 1999
• The agreement outlines co-operation with regards
  to such issues as commercial, technical, tactical
  info
• Phase 1 of the Project Agreement defines a
  co-operation until end 2003. Phase 2 (under
  preparation) shall cover all activities related
  to Full Development until 2007

Government Co-operation
Industrial Co-operation

• Swedish FMV and Finnish DFMC are active partners
• Danish HMAK and Norwegian FLO/Land are observers
• Canada have applied for observer status

• Finnish Patria Hägglunds OY is the prime
  contractor.
• Patria Weapon Systems and Alvis Hägglunds are sub
  contractors and do all principal work (also
  owners of PH)

• 2x10 rds
• Automated loading functioning.
• Chassis
• New installedin Dec-02, containing 40 rds

25
Current Status of FCS

• Swedish ballistic kernel
• Fully integrated GPS aided inertial navigation
  system
• Integrated digital data message formats from FO
• MMI with map display (land version)

• Capable of continuous calculation to enable fire
  on the move/at moving targets
• MMI with map display (land version)
• Automated handling of
• MET
• Different targets
• Up to 4 different fire missions simultaneously
  (land version)

27
SSG120 Navy Application
Turret on Combat Boat 90

• Joint Army/Navy programme to be in full operation
  from SDD (PDF)
• Primary focus of tests is put on
• Firing precision and accuracy
• Fire on the move
• Tests also focused at subsystem compatibility
  FCC, INSGPS, MMI
• SSG120 Navy will take full advantage from
  experience for the Army version
• Worlds first truly remotely controlled mortar
  turret
• Objective also to pave the way for firing on the
  move with SSG120 Army version

28
Areas of Particular Concern

• Today's ammunition
• Only qualified for transport in original boxes
• Not optimised for breech loading and direct fire
• Needs a man in the loop
• Fuzes
• No inductive setter developed and tested
• No inductive setting fuze developed for direct
  firing
• Stub case
• Logistic tail
• System responsibility

29
Requirements Summary

• Winter and summer trials successfully conducted
  by Swedish Army Combat School
• The SSG120 is fully autonomous and automated
• The SSG120 can fire on the move at moving targets
• The SSG120 has a significant development potential

SSG120 meets TRL7 todayTRL Technology Readiness
Level in accordance with US definition
30
Programme Summary

• SSG120 will be the Indirect Direct Firepower
  for National International Manoeuvre Battalions
  and Amphibious Task Units
• SSG120 aims at Net-centric integration
• SSG120 supports both Precision Engagement and
  Area Engagement
• SSG120 is Responsive and Accurate
• SSG120 is a fully funded programme throughout
  series production

SSG120 has proven exceptional performance and is
showing great potential for future development
