APEX
PEREGRINE-E
5,285 lb MTOW · 250 KTAS · 100 NM one-way / 200 NM RT · ~59 dB(A) at 500m
PROGRAM OVERVIEW
The Apex Peregrine-E is the pure-electric military variant of the Peregrine airframe. It shares the identical fuselage structure, 15-ft swept-tip rotor system, nacelle tilt mechanism, and emergency safety systems as the standard Peregrine Rev D — but replaces the Nelson LS427 TT genset and fuel system entirely with a 233 kWh Amprius SiNx anode battery pack.
Without the turbocharged V8 engine, the Peregrine-E's only noise source is rotor blade passage. At 500 m in cruise, the aircraft produces approximately 59 dB(A) — equivalent to a quiet conversation. In any outdoor environment with ambient wind, it is acoustically undetectable beyond 400 m. There is no exhaust plume, no heat signature from engine combustion, and no electromagnetic emissions from ignition systems.
The Dillon Aero M134D-H minigun in a retractable ventral turret delivers 3,000 rounds per minute of 7.62×51mm NATO across a ±120° arc, with FLIR Star SAFIRE 380-HD day/night targeting. Four YASA 400 drive motors run at just 36% of continuous rated power in cruise — the aircraft is not power-limited in any operational regime.
Removing the 842 lb engine and fuel system — and one pair of generator motors — saves more weight than the 1,352 lb battery adds. The Peregrine-E is 751 lb lighter at MTOW than the standard Peregrine (5,285 lb vs. 5,891 lb), with superior hover margins (+87.8% continuous vs. +80.6%) and lower disk loading (7.27 vs. 8.33 lb/ft²). The 233 kWh pack uses Amprius SiNx anode cells at 380 Wh/kg pack level — the highest energy density in production aviation-grade cells as of 2025.
ACOUSTIC ADVANTAGE
The Peregrine-E's acoustic profile is defined entirely by rotor blade passage — the same fundamental noise floor as any helicopter. The engine, exhaust, and combustion noise that dominates conventional rotorcraft are completely absent.
Detection range assumes ambient outdoor noise of 40–45 dB(A) with light wind. In jungle or urban environments with higher ambient noise, the Peregrine-E may be undetectable beyond 200 m.

MISSION PROFILES
Special Operations EXFIL/INFIL
The Peregrine-E is forward-deployed by the Apex Pelican as a sling load to a staging point within 100 NM of the objective, with 100 NM one-way / 200 NM round-trip from staging. With no engine noise, the aircraft is acoustically undetectable beyond 400 m — quieter than ambient wind. Four operators insert or extract at 250 KTAS, with the M134D belly turret providing suppressive fire during ingress and egress.
PELICAN FORWARD DEPLOYMENT
The Peregrine-E is forward-deployed by the Apex Pelican using the HR-PKG-001 Rapid-Deployment Container System (RDCS) — a 4130 chromoly steel frame with hydraulic rotor-fold mechanism and dual-redundant pyrotechnic panel release. The Pelican slings the packaged aircraft to a staging point up to 100 NM from the objective, sets it down, and the Peregrine-E self-deploys in under 3 minutes with no ground crew. The Pelican then returns to base or holds at altitude as a communications relay.
MEDEVAC CONFIGURATION
The Peregrine-E converts to a MEDEVAC configuration by removing the Dillon Aero M134D-H turret assembly and ammunition system (−411 lb) and installing a single-litter medical kit with onboard oxygen, defibrillator, and IV administration capability (+85 lb net). The conversion is field-reversible in under 45 minutes by two technicians.
The Peregrine-E's ~59 dB(A) acoustic signature at 500 m is clinically significant in the MEDEVAC role. Conventional helicopter noise (88–93 dB(A)) causes measurable patient stress responses and impairs medical team communication. The Peregrine-E operates below the 65 dB(A) threshold associated with stress-induced physiological responses, improving patient outcomes during transport.
MISSION ENERGY BUDGET
The 233 kWh battery pack is sized for a complete military mission with 20% reserve. The chart below shows how energy is allocated across each phase of the standard 100 NM one-way (200 NM round-trip) exfil/infil mission profile.
