NAVAL PATROL AIRCRAFT
Long-range maritime patrol aircraft designed to locate and destroy submarines and surface vessels. Its supplied progression combines increasing anti-ship and anti-submarine attack with expanding sonar coverage, longer flight range, stealth-submarine detection and cruise-missile capability from Level 4 onward.
Eastern Family
Tu-142 → Il-38 → A-40
Western Family
P-3 → CP-140 → P-8
European Family
Nimrod → CN-235 → C295
Primary Role
ASW / Anti-Ship
Maritime Patrol Capability // Specialist
The supplied source treats the displayed radar-range field
as sonar range for this aircraft. Naval Patrol Aircraft also
carries a dedicated stealth-submarine reveal capability.
Cruise-missile launch capability begins at Level 4 and remains
separate from normal anti-ship and anti-submarine attack values.

Select Doctrine & Level
Select doctrine and Level 1–5. Combat values are shared
across all three supplied doctrine profiles; doctrine
selection changes aircraft-family identity while level
selection updates the confirmed operational and combat data.

Detection System
Sonar
The source explicitly identifies the displayed radar-range
field as sonar range for Naval Patrol Aircraft. The confirmed
progression is 75 → 100 → 150 → 150 → 200.
Detection Capability
Reveal Stealth Subs
Stealth-submarine reveal is a dedicated detection capability
and is not treated as an attack value.
Weapon Capability
Not Available
Cruise-missile launch capability is confirmed from Level 4
onward. No missile damage value is merged into normal combat.

Maritime Hunter Profile
Anti-Submarine
Submarine attack rises from 5 at Level 1 to 8 at Level 5.
Sonar coverage expands from 75 to 200, while the aircraft
carries a dedicated stealth-submarine reveal capability.
Anti-Surface
Surface-ship attack rises from 7 to 14 across the supplied
progression, giving the aircraft a confirmed anti-surface
strike role alongside its submarine-hunting mission.
Long-Range Patrol
Flight range grows from 1,500 to 3,500. This operational
reach is kept separate from sonar detection radius.
Cruise Missile
Level 4 and Level 5 aircraft are confirmed cruise-missile
capable. This mechanic remains separate from direct
anti-ship and anti-submarine attack values.
Source Separation // Important
The supplied doctrine trees show the same core combat progression
for Eastern, Western and European Naval Patrol Aircraft. Aircraft
family names are therefore doctrine-specific, while confirmed
level combat values remain shared. The source presents three
aircraft families across five levels but does not explicitly map
every individual airframe to a specific level, so no unsupported
level-to-platform assignment is shown. Research is presented as
confirmed tree milestones rather than forcing those dates into
an unsupported exact level mapping.
