RAAF Potential Areas of Interest

Why Unmanned, Stealthy, and Refuelable?
•Massive increase in mission/combat endurance
•Enhanced survivability in persistent operations
•No aircrew capture/casualty risk
•Significant potential cost-effectiveness
advantages—particularly life-cycle cost
Decoupling the Human from the Aircraft to Increase Capability, Decrease Cost/Risk

Range requirement a result of:
• Threat analyses: how much range is enough?
• Tankers: stand off distance from threats

Endurance ~ Persistence
• Aerial refueling allows optimal balance
between endurance and payload
• 8-10 hour endurance (unrefueled)
tactical air vehicles are feasible

EnduranceRange
Survivability
Stealth: Broadband and All Aspect
• Rqt based solely on projected threat analysis
• Not retrofittable – set with airframe design
10 Approved for Public Release: NG18-1782, 8/17/18

Survivability: The Kill Chain
11
Progression through the kill chain involves transition
from low-frequency surveillance radars
to medium/high-frequency targeting radars

EnduranceRange
12
Multi-role Mission Payloads
• ISR/T – EW – STRIKE
• Flexible payload bays
• Both air-to-surface and air-to-air roles

• The manned system makes single ingress into
defended airspace (and is forced off station by
aircrew endurance limit).
• The manned system total sortie cycle time is
12.0 hours, generating 2.2 hours on station.

Advantage of Unmanned Aircraft
Don’t Buy To Train – Don’t Fly To Train
therefore
Don’t Buy As Many – Don’t Fly As Much
