UAS as an Enabler for EW Effects Delivery
• UAVs Provide “Access”: (i.e. “Go where other Systems can’t”)
– Access to Typically Denied Areas:
• Protected Areas (Detection & Defense Systems)
• Distant / Deep Locations (Not Plausible with Current Access Methods)
• “Politically Protected” Areas
– “Close-in” Air Space (Very-Close Airspace is now Achievable)
– Undetectable via Small Size, Slow Speeds, LPI Signatures
– Access through numbers (Many Locations at Once)
• Decrease Risk:
– The Human is out of Reach
– Access with Attritable or even Expendable Assets
• Don’t Break the bank when we lose a platform
• Lower Costs:
– UA Platform may be lowest cost Item in Kill Chain
• Persistence: (i.e. “Stay where other Systems can’t”)
– Long Loiter – “Remain on Location”

J/S = (Pj * Gjr * Grj * Rtr2 * Lr * Br)/(Pt * Gtr * Grt * Rjr2 *Lj * Bj) Where, Pj= RF Jammer Power Pt= Transmitter Power Gjr= Antenna Gain from Jammer to the Receiver Grj= Antenna Gain from Receiver to the Jammer Gtr=Antenna Gain from Transmitter to the Receiver Grt= Antenna Gain from Receiver to Transmitter Br= Communications Receiver Bandwidth Bj= Jamming Transmitter Bandwidth Rtr= Range Between Communication Transmitter and Receiver Rjr= Range Between Jammer and Communication Receiver Lj= Jammer Signal Loss, this Includes Polarization Loss Lr= Communication Signal Loss

Cross-industry team of Insitu, Motorola, and NGC successfully demonstrated
feasibility of Airborne Electronic Attack from Group 3 UAS
MFEW - UAS Offensive Electronic Attack
OSD Vigilant Hammer 2 (VH2) Demo
Overview
Project Description • Design, build and fly a OEA payload for the Bat Group 3 UAS
at the OSD sponsored VH2.
• Demonstrate OEA against “Near-Peer” Radios in a tactical environment, (threats from the MFEW CDD)
• Demonstrate Manned Unmanned teaming in a cooperative EA mission against radar (threats also listed in the MFEW CDD).
Group 3 UAS EA Objectives
• Counter Comm and Counter Radar – without reconfiguration
• MUM-T EA with 4th Gen/5th Gen Fighters
• Counter Near Peer radio • Rough measure of effects
• Determine TTPs going forward
• Survey VHF/UHF Environ for post analysis
• Demonstrate Tech Readiness for MFEW Air Small
