Background
• SPEAR
– Selective Precision Effects at Range (SPEAR) is the Ministry of Defence’s
(MoD) research and development request for highly accurate, beyond visual
range re-targetable weapons which can receive target information updates
over a data-link (network) in near real-time as part of the UK’s “Network
Enabled Capability” (NEC) [1].
• NEC
– “Network Enabled Capability (NEC) offers decisive advantage through the
timely provision and exploitation of information and intelligence to enable
effective decision-making and agile actions. NEC will be implemented
through the coherent and progressive development of Defence equipment,
software, processes, structures, and individual and collective training
underpinned by the development of a secure, robust and extensive network
of networks.”[2]

Background
• Current state of SPEAR
– SPEAR Cap 1: Paveway Guided Bomb
– SPEAR Cap 2: Powered Missile
– SPEAR Cap 3: Requirement for retargeting via data links.
• MoD research on fitting PGB and Powered Missiles with data links has
already been carried out.
• Not unreasonable that the MoD might try to retrofit data link capabilities
into existing systems.
Why we are doing this
• To investigate:
– Whether and how these systems can be used safely and reliably!
– Improve the ability of the operator and pilot to make the correct decisions in
the time required.
– Providing methods to reduce the risk of collateral damage.
Simulating Networked Weapon Systems
• Setup
– Weapon – Generic Guided Bomb Unit (GBU)
– Delivery Mechanism – Tornado GR4 (Piloted)
– Target – Generic SAM Launcher
– Intelligence Source – MQ-9 Reaper UAV Video Feed
– Remote Operator - HUMAN
• Simulation Software:
– Aircraft Simulation – FlightLAB (ART) & X-Plane 10
– Visualisation Suite – X-Plane 10
– Weapon Simulation – MATLAB
– Networking – Visual Studio & MATLAB
Remote Operator Terminal
Tornado GR4 Fast-Jet
Attack Aircraft
MQ-9 Reaper UAV
Intelligence: Eyes on Target
GBU
Guided Free-fall Weapon
Remote Operator Terminal
Re-tasking Weapons
The Re-Tasking Acceptability Region (RAR)
NEW TARGET:
Lat: 51.243370̊N
Lon: 00.589538̊W
Alt: 00060 Meters
RAR
• The Dynamics of RARs
T = 0 seconds T = 22 seconds T = 26 seconds
T = 27 seconds T = 31 seconds
Release at ≈
20’000ft
Impact at 38
seconds
Testing Decision Making
• The Sample Population’s Task:
– To Correctly Re-Task or Deny a Re-Task Request dependant on
whether the weapon will accurately hit the target.
Re-Task
O.K.
Re-Task
FAIL
Testing Decision Making
• Variables
– Distance of New Target from Original Target
– Bearing of New Target from Original Target
– Time From Launch of Re-Task Request
Testing Decision Making
• Test Variables:
– Speed at which the operator can make a decision to re-task the weapon?
– Was it the correct decision?
– What was their mood/stress level?
– How confident were they that they made the correct decision?
– How good was their situational awareness?
Testing Decision Making
• Design the H.M.I. to help Operators make the “correct” decision.
• Best way to display the collapse of the RAR to the Operator?
• Types of Display:
– RAR Area Plot on Map.
– Moving Graph of Area % Remaining.
– Maximum Reachable Range from Current Ballistic or On-Target Trajectory.
– Projection of Future RAR on Map.
Summary
• Simulation Suite of Weapons and Aircraft
– GBU Weapon Simulation
– Fixed Wing Aircraft (Tornado, Typhoon, Jetstream etc)
– Helicopters
• Development of a General Remote Operator Terminal Successful
– Moving Map
– Live Video Feed
– Verbal Communication Network (e.g. Radio)
– Can Transmit Target Updates to Weapon
– Overlay of LAR and RAR regions along with asset and target locations
• Moving into Trials
– Testing Decision Making of Remote Operators of Networked Weapons
