The Radar Cross Section (RCS) of the Chengdu J-10C is estimated to be between 1m² and 3m², depending on configuration and angle of detection.

Factors Affecting J-10C RCS:

1. Diverse RCS Estimates:

• Older J-10A/B models have an RCS of ~5m² (comparable to an F-16).

• The J-10C, with its stealth improvements, reduces RCS to 1-3m² (some estimates suggest even as low as 0.5m² in optimal conditions).

2. Stealth Enhancements:

• Diverterless Supersonic Inlet (DSI) reduces frontal radar reflections.

• Radar-absorbing materials (RAM) on key surfaces.

• Internal structuring and RAM coatings reduce RCS but don’t make it fully stealthy.

3. External Load Increases RCS:

• When carrying external weapons, fuel tanks, or targeting pods, the RCS can increase significantly (possibly to 5m² or more).

• If loaded clean with only PL-15 missiles in semi-recessed mounts, RCS stays lower.

Comparison with Other Fighters:

Conclusion:

The J-10C has a lower RCS than most 4th-gen fighters due to RAM coatings and DSI inlet, but it is not a stealth aircraft. It is still detectable by modern AESA radars but has some level of radar signature reduction compared to legacy fighters.

To estimate the detection range of the J-10C’s AESA radar against the Su-30MKI and vice versa, we use the radar range equation, particularly considering RCS and radar types:

1. J-10C (KLJ-7A AESA Radar) Detecting Su-30MKI

• J-10C's AESA radar (KLJ-7A or newer version)

• Estimated detection range vs 5m² target: 150 km

• Estimated peak power: 8-10 kW

• Su-30MKI RCS: ~20m² (with external stores)

Since RCS increases by a factor of 4 compared to a 5m² target, the detection range increases:

✅ J-10C should detect Su-30MKI at approximately 175-180 km.

2. Su-30MKI (N011M Bars PESA Radar) Detecting J-10C

• Su-30MKI's N011M Bars PESA radar

• Detection range vs 5m² target: 140 km

• Peak power: 4-5 kW

• J-10C RCS: ~1-3m²

Since RCS is lower than 5m², detection range decreases:

For J-10C at 3m² RCS:

For J-10C at 1m² RCS:

✅ Su-30MKI should detect J-10C at approximately 100-125 km.

Key Takeaways

1. J-10C (AESA) detects Su-30MKI first at ~175-180 km.

2. Su-30MKI (PESA) detects J-10C later at ~100-125 km.

3. AESA radar gives J-10C a major advantage, as it is more resistant to jamming and has better tracking capability.

4. BVR advantage: J-10C, equipped with PL-15 (200+ km range), can engage first before Su-30MKI can retaliate with R-77 (110 km max).

Overall Conclusion

J-10C holds the advantage in radar detection, tracking, and BVR combat, making it superior in a head-to-head beyond-visual-range (BVR) engagement.

Absolutely! Let's analyze the detection range between the J-10C (AESA radar) and Rafale (AESA radar in IAF service) using the same approach as before.

1. J-10C (KLJ-7A AESA) Detecting Rafale

• J-10C AESA radar (KLJ-7A or newer version)

• Detection range vs 5m² target: 150 km

• Peak power: 8-10 kW

• Rafale RCS: ~0.1 - 0.5m² (with stealth optimization, clean)

Since Rafale’s RCS is significantly lower than 5m², detection range decreases:

For Rafale at 0.5m² RCS:

For Rafale at 0.1m² RCS (best-case stealth scenario):

✅ J-10C should detect Rafale at approximately 80-110 km, depending on Rafale’s configuration.

2. Rafale (RBE2-AA AESA) Detecting J-10C

• Rafale AESA radar (Thales RBE2-AA)

• Detection range vs 5m² target: 200 km

• Peak power: 10+ kW

• J-10C RCS: ~1-3m²

For J-10C at 3m² RCS:

For J-10C at 1m² RCS:

✅ Rafale should detect J-10C at approximately 140-180 km.

Key Takeaways

1. Rafale detects J-10C first at 140-180 km, while J-10C detects Rafale later at 80-110 km.

2. Rafale has a radar and stealth advantage, giving it better BVR engagement capability.

3. BVR Missiles:

• J-10C uses PL-15 (200+ km range, AESA-guided)

• Rafale uses Meteor (150-200 km range, AESA-guided, ramjet-powered for high endgame energy)

• Meteor’s no-escape zone is significantly larger than PL-15 due to its sustained propulsion.

Final Conclusion

• Rafale has a clear advantage in BVR combat due to superior radar, lower RCS, and Meteor missile.

• J-10C is still highly capable and benefits from PL-15’s range, but its radar detection delay vs Rafale is a disadvantage.

• If both aircraft detect each other simultaneously (e.g., with AWACS support), it would depend on pilot tactics and electronic warfare capabilities.

✅ Verdict: Rafale is superior in a 1v1 BVR scenario, but J-10C is still a potent adversary.

Great challenge! You're absolutely right—real-world combat scenarios involve external weapons and fuel tanks, which significantly increase RCS and detection ranges. Let’s now recalculate the detection ranges for both J-10C and Rafale while carrying weapons (BVR and WVR missiles).

RCS Adjustments for Combat Loadouts

• J-10C with 6 missiles (4x PL-15, 2x PL-10) → RCS increases to ~5m²

• Rafale with 6 missiles (4x Meteor, 2x MICA) → RCS increases to ~10m²

1. J-10C (KLJ-7A AESA) Detecting Rafale (RCS = 10m²)

• J-10C’s AESA radar (KLJ-7A or newer version)

• Base detection range vs 5m² target: 150 km

• Since Rafale’s combat RCS is 10m², the detection range increases:

✅ J-10C can detect Rafale at ~175-180 km in combat configuration.

2. Rafale (RBE2-AA AESA) Detecting J-10C (RCS = 5m²)

• Rafale’s AESA radar (Thales RBE2-AA)

• Base detection range vs 5m² target: 200 km

• Since J-10C’s combat RCS is 5m², detection range remains close to 200 km:

✅ Rafale can detect J-10C at ~200 km in combat configuration.

New Detection Range Summary

Key Takeaways in Combat Scenario

1. The detection gap is reduced:

• In stealthy configuration, Rafale was detected at 80-110 km, but in combat configuration, J-10C detects it at ~180 km.

• This means Rafale loses much of its stealth advantage once fully armed.

2. Rafale still has the radar edge:

• Rafale’s RBE2-AA AESA is slightly more advanced than J-10C’s KLJ-7A AESA and maintains a longer detection range (~200 km vs. ~180 km).

• This means Rafale will still detect J-10C first, but now the difference is just ~20 km instead of 60-100 km (when Rafale was clean).

3. Missile Engagement & BVR Combat

• Meteor (Rafale, 150-200 km range) vs. PL-15 (J-10C, 200+ km range)

• In theory, J-10C could fire first due to the PL-15's longer nominal range.

• However, Meteor has superior endgame energy (ramjet sustains speed), making it more lethal than PL-15.

Final Verdict in Real-World Combat

1. J-10C now has a better chance in BVR engagements due to the loss of Rafale's stealth advantage.

2. Rafale still holds the upper hand due to its more powerful AESA radar and Meteor missile's better terminal performance.

3. Both aircraft will detect and engage each other at roughly the same time (~180-200 km), making pilot training, electronic warfare, and AWACS support the deciding factors.

✅ In combat configuration, the gap between J-10C and Rafale is smaller, but Rafale remains superior in BVR combat due to its radar and Meteor missile advantage.

Yes, that's actually a valid hit-and-run tactic for the J-10C in a BVR engagement against the Rafale. The "shoot-and-scoot" strategy would be based on the following key advantages of the J-10C:

J-10C's Best Strategy vs Rafale

1. First Lock & Fire Advantage:

• Since J-10C can detect Rafale at ~180 km, it can lock on and fire first before Rafale fully detects it (~200 km).

• The PL-15 missile (200+ km range, AESA-guided) allows the J-10C to fire preemptively at max range.

2. Missile Spam (Multiple PL-15s):

• Fire 2-4 PL-15s immediately at max range (~180 km) before Rafale gets full lock.

• This forces Rafale into defensive maneuvers, reducing its ability to counterattack effectively.

• Even if PL-15’s kill probability is lower than Meteor, multiple launches increase the chance of a successful kill.

3. Full Afterburner Escape:

• Turn 180° immediately after missile launch and retreat at Mach 1.8+ using full afterburner.

• Reduce RCS by minimizing exposure time to Rafale’s tracking radar.

• Use electronic countermeasures (ECM) and chaff to break any missile lock.

Limitations of This Strategy

• PL-15's real kill probability is unknown:

• Meteor’s ramjet sustains high terminal speed, while PL-15 loses energy in the endgame.

• This means even if J-10C fires first, Rafale’s Meteor could be more effective if it survives the initial attack.

• J-10C must rely on speed to escape:

• J-10C has no supercruise, meaning it must use afterburners, which burn fuel quickly and limit combat endurance.

• If Rafale survives, it will chase down the J-10C:

• Rafale has better sustained maneuverability and supercruise (can fly Mach 1.4 without afterburners), meaning it can catch a fleeing J-10C in some scenarios.

Final Assessment: Will This Strategy Work?

• Yes, in certain conditions:

• If J-10C fires at max range (180 km) and Rafale is not expecting an attack, it could force Rafale into a defensive posture, disrupting its ability to retaliate effectively.

• If J-10C is supported by AWACS (which extends tracking range), it could time the attack for maximum advantage before Rafale fully detects it.

• No, if Rafale anticipates the attack:

• If Rafale detects J-10C early, it can counter-fire with Meteor before J-10C escapes.

• Rafale’s superior ECM and maneuverability increase its chances of surviving PL-15s, after which it can chase down and engage the J-10C at closer range.

✅ Best Scenario for J-10C:

1. Use AWACS to track Rafale early.

2. Fire multiple PL-15s at max range (~180 km).

3. Immediately turn away and flee using afterburners.

4. Use ECM, chaff, and maneuvering to evade Meteor counterattack.

🚨 However, if Rafale survives the missile volley, J-10C will be at a serious disadvantage in a close-range dogfight.

You're absolutely right! The "no-escape zone" (NEZ) for Meteor is around 60-80 km, meaning that if J-10C launches PL-15s from 180 km and immediately turns away, it has a good chance to escape before entering Meteor’s high-probability kill zone.

Breaking Down the BVR Timeline for J-10C vs Rafale

Key Advantages for J-10C in This Hit-and-Run Strategy

1. PL-15 forces Rafale into a defensive posture

• Rafale must react first by dodging and using countermeasures before launching its own missile.

• This disrupts Rafale’s ability to fire Meteor at the best conditions.

2. J-10C exits Meteor’s NEZ before it reaches full kill probability

• Meteor is deadly inside 80 km, but outside of that, it slows down.

• If J-10C fires first and immediately turns away, Meteor loses energy while chasing a fleeing target.

• J-10C’s ECM and maneuvers further reduce Meteor’s effectiveness.

3. Rafale’s Meteor might not be effective at long range

• If fired from 140-160 km, Meteor is still in its early flight phase and may not have enough energy to catch a retreating J-10C.

• Meteor is most lethal inside 80 km, where its ramjet still has power to maneuver aggressively.

Conclusion: Can J-10C Escape?

✅ Yes, J-10C can escape if:

• It fires PL-15 first (180 km) and turns away immediately.

• It moves outside Meteor’s NEZ before Meteor reaches it (~120 km distance or more).

• It uses ECM and maneuvering to avoid the final impact phase.

🚨 However, J-10C is still at risk if:

• Rafale dodges PL-15s and launches Meteor effectively (~100 km or less range).

• AWACS or friendly fighters keep tracking J-10C’s escape path.

• Meteor is launched within 80 km, where it’s almost impossible to evade.

Final Verdict

🔥 J-10C’s "fire and flee" tactic is a solid strategy against Rafale’s Meteor!
🔹 It avoids the worst-case scenario (Meteor inside 80 km).
🔹 It disrupts Rafale’s attack sequence, forcing it defensive.
🔹 J-10C can use speed, ECM, and distance to escape BVR retaliation.

🚀 However, if the fight moves within 80 km, J-10C is in serious trouble, as Meteor becomes nearly inescapable.
