Xianren People's Air Defense Forces¶
The Xianren People's Air Defense Forces (XPADF) — Renmin Kongjun — are the Federation's principal air and air-defence service. At approximately 240,000 active personnel and ~130,000 trained reserves, the XPADF is one of the world's five largest air services and is the world's largest single national integrated air-defence system operator. The service's name reflects the Federation's doctrinal orientation: XPADF integrates offensive air operations with strategic air defence in a single command structure, in contrast to the FSA and the Federation of Hinomura where these functions are institutionally separated.
Organisation¶
The XPADF is organised as five theatre air commands distributed across the Federation's theatre command structure, plus a Strategic Air Command at CMC level.
Theatre air commands¶
| Command | Home theatre | Principal focus |
|---|---|---|
| Eastern Air Command | Eastern Coastal Theatre | Sea of Xianren counter-Hinomura posture; principal fighter and strike concentration |
| Southern Air Command | Southern Coastal Theatre | Sea of Pelawan; Malavanu / Sangharan / Ryukai approaches |
| Northern Air Command | Northern Theatre | Choktovakian frontier; northern-shelf commercial-shipping-lane cover |
| Interior Air Command | Interior Theatre | Strategic-air-defence depth; strategic bomber basing |
| Southwestern Air Command | Southwestern Theatre | Nanjun autonomous-region cover; southern approach depth |
Strategic Air Command¶
Reports directly to CMC. Comprises:
- Strategic Bomber Wing — H-6K and H-6N nuclear-and-conventional strategic bombers
- Strategic Air-Refuelling Wing — Y-20U tanker aircraft; Federation-produced Il-78 successors
- National Command Air Wing — VIP and senior-leadership transport; airborne command post
- Strategic ISR Wing — Y-20-based signals-intelligence and airborne early warning
Wing / squadron structure¶
Below the theatre-command level, XPADF forces are organised as wings and regiments (equivalent to Sierran-Western "wings" — the terminology varies by service tradition). Each wing typically comprises three to four squadrons of approximately 24 aircraft each, plus attached support squadrons.
Fighter and strike aviation¶
The XPADF fighter and strike inventory at Turn 3:
| Type | Role | Count | Notes |
|---|---|---|---|
| J-20 Chishan | Fifth-generation stealth fighter | ~280 (+40/year production) | Federation's flagship air-superiority platform; roughly F-22 / F-35 class |
| J-16 | Multirole strike-fighter | ~420 | Federation Su-30MK2-derived multirole |
| J-11B/BS | Air-superiority fighter | ~280 | Federation Su-27 derivative |
| J-10C | Multirole medium fighter | ~460 | Federation domestic-designed medium fighter |
| J-15 | Carrier multirole fighter (XPNF) | (~120 XPNF) | Reference: operated by naval aviation, listed here for completeness |
| JH-7A | Strike-fighter | ~120 | Older-generation strike; being phased out |
| J-35 | Fifth-generation carrier fighter (XPNF) | (~40 XPNF) | Reference: operated by naval aviation |
| H-6K/N | Strategic bomber | ~230 | Federation Tu-16-derived strategic bomber; carrier of the CJ-20 strategic air-launched cruise missile |
| KJ-500 | Airborne early warning + control | ~30 | Federation E-3-class AEW&C |
| KJ-2000 | Legacy airborne early warning | ~4 | Being retired |
| Y-20 (transport) | Heavy strategic transport | ~85 (+8/year production) | Federation C-17 equivalent |
| Y-9 | Medium tactical transport | ~110 | Federation C-130-class tactical transport |
| Y-20U | Air-refuelling tanker | ~24 (+6/year production) | Federation strategic tanker |
| Y-8Q / GX | Maritime patrol / SIGINT | ~45 (XPADF + XPNF) | Reference |
The J-20 Chishan¶
The J-20 Chishan ("Crimson Mountain") is the Federation's principal fifth-generation air-superiority platform and is the Federation's most-visible strategic-military-technology achievement of the past decade. The J-20 entered service in 2017 and is produced by Chengfei Aviation Industrial Group on a growing production line. The programme is a Federation civil-military-fusion showcase — Chengfei is a state-owned aerospace prime that produces both military and commercial aircraft; the J-20 has drawn on Federation-domestic advances in engine technology (WS-15 turbofan, entering series production in 2024), stealth composites, and integrated sensor systems.
J-20 doctrinal role: air superiority in contested airspace; long-range air-to-air interception of high-value air targets (tanker aircraft, AEW, strategic bomber); penetration of hostile IADS environments.
The J-35 (carrier-based)¶
The J-35 is the Federation's fifth-generation carrier-based multirole fighter, produced by Shenfei Aviation Industrial Group and entering XPNF service from 2026. Distinct from the J-20 (which is XPADF-only, land-based-only): the J-35 is the carrier-air-wing fifth-generation replacement for J-15B. Roughly F-35 class in capability profile.
The H-6K/N strategic bomber¶
The H-6K/N is the Federation's principal strategic bomber — a substantial modernisation of the earlier H-6 airframe (which was itself a Federation-manufactured Tu-16 derivative). The H-6K provides conventional strike (CJ-20 air-launched cruise missile; 1,500+ km range) and nuclear strike (CJ-20A nuclear-warhead variant). The H-6N is a further modernisation with air-refuelling probe and enlarged weapons bay; approximately 50 in service.
Federation strategic-bomber doctrine treats the H-6K/N as a strategic-strike anchor, complementing Rocket Force conventional and nuclear missile forces. Strategic-nuclear-triad participation runs through the H-6N.
Air defence¶
The XPADF operates the world's largest single-nation integrated air-defence system (IADS) — a networked, multi-layer surface-to-air missile and radar system providing overlapping coverage of the Federation's coastline and principal interior population and industrial centres.
Principal SAM systems¶
| System | Range | Role |
|---|---|---|
| HQ-9B / HQ-9C | Long range (200+ km) | Strategic long-range SAM; Federation equivalent of Patriot / S-400 |
| HQ-19 | Long range with terminal-phase ballistic-missile-defence | Federation domestic BMD system |
| HQ-22 | Medium range (170 km) | Deployable medium-range SAM |
| HQ-16B | Medium range (70 km) | Divisional SAM (also operated by XPGF) |
| HQ-17 | Short range (15 km) | SHORAD |
| HQ-6B | Very short range | Point-defence |
| PGZ-95 | AAA + SHORAD | Point-defence AAA |
Federation SAM production is a Federation civil-military-fusion priority sector — Federation SAM output has been the largest single-national SAM production for the past decade and Federation SAM export is one of the largest single national arms-export categories.
The integrated radar network¶
The IADS radar network combines:
- Type-609 long-range early-warning radar — Federation strategic-early-warning system; substantial installations across the coastal-belt and interior depth
- Type-517A phased-array radar — theatre-level air-defence tracking
- JY-27A anti-stealth radar — Federation VHF-band anti-stealth radar; regarded internationally as the most-capable non-Sierran anti-stealth radar system
- Type-305A / Type-305B — deployable air-defence acquisition radars
- JY-11 Ozone — battlefield air-defence radar
- Space-based ISR through the Federation's satellite constellation
The counter-Hinomura air-defence problem¶
XPADF air-defence doctrine facing Hinomura has to solve for the specific problem of Hinomuran offensive air capability:
- Hinomuran F-22 — the only F-22 operator outside the FSA; roughly 24 airframes; range and stealth adequate to threaten Federation Eastern-Coastal-Theatre airspace
- Hinomuran F-35A — expanding fleet; multi-role fifth-generation
- Hinomuran F-2 — carrier of Type-12 air-launched anti-ship missile
- Hinomuran F-15J(EX) — modernised legacy fleet
Federation counter-Hinomura air-defence relies on:
- HQ-9B/C long-range coverage of the near-coastal zone
- JY-27A anti-stealth radar targeting F-22 / F-35 stealth signature
- J-20 fighter cover as the outer offensive-defensive layer
- IRST-based passive detection to complement radar (Federation IRST technology has been substantially advanced in the past five years)
Doctrine¶
Integrated air operations¶
XPADF doctrine treats integrated air operations — the coordinated employment of offensive-counter-air, defensive-counter-air, strategic-strike, air-mobility, and ISR — as the operational unit of modern air campaigning. The XPADF's institutional integration of air-defence and air-strike functions is the doctrinal manifestation.
The IADS as the national protective envelope¶
The Federation IADS is doctrinally treated as the national protective envelope — the layer of Federation strategic defence that protects Federation industrial, population, and command centres from external air attack. Federation strategic-air-defence policy assumes that the IADS is the single-most-important passive component of Federation strategic defence and that its integrity must be maintained through the earliest phases of any conflict.
Strategic-strike depth¶
XPADF strategic-strike doctrine emphasises long-range conventional strike as a strategic instrument that operates below the nuclear threshold. Federation air-launched cruise missiles (CJ-20 family), Rocket Force conventional ballistic missiles, and Federation coastal ASM force between them provide a strategic-strike capability that can reach targets throughout the Sea of Xianren and the near-coast Hinomuran archipelago without nuclear escalation. This is the Federation's principal strategic-strike-below-threshold instrument.
The Y-20 heavy transport programme¶
The Y-20 Kunpeng ("Great Roc") heavy strategic transport is one of the Federation's principal civil-military-fusion showcases. The Y-20 provides:
- Strategic troop-and-equipment transport (~66 tonnes payload, ~7,800 km range)
- The base airframe for the Y-20U air-refuelling tanker
- The base airframe for planned KJ-3000 next-generation AEW aircraft
- The base airframe for planned Y-20-based SIGINT / EW aircraft
Federation strategic-lift capability at Turn 3 is substantially less than FSA strategic-lift capability but has grown from effectively zero in 2013 to roughly 35% of FSA strategic-lift today. Federation strategic-lift growth is one of the principal enablers of the Federation's expanding strategic reach.
