Hangor Class Submarine | Updates & Discussion

Not implausible completely, even a cannisterized missile (like the CM-708 UNB just launched) is fired in a ballistic manner.

Nothing is implausible, but why would you even try to adapt a ballistic missile the size of smash into torpedo tube lunched? There's a significant difference between a small booster to launch a cruise missile from torpedo tubes and launching a large BM. There's probably a good reason why even the likes of North Korea never bothered, but I guess the PN is proving the world wrong lol

Watch the screen.

This is awesome. We can already see where this is headed.

Exactly, that's why I asked: why this C70xUxx when we have Harba, Smash, etc.? What additional capability does this bring to the table?

You don't read reply and again ask same question ?

Below is clear answer to Why this and why not harbah, smash etc.

- SMASH, so far is ship/land launched. Submarine variant is highly unlikely, will require design change.

- Babur-III: Its already available but its not Anti-Ship missile. Its land attack missile.

- Harbah: No submarine launched version available.

- P282: ? I was telling everyone including "think tank" members years before that P282 and SMASH are one and same missile. The SMASH is the P282.

So obviously, Hangors needed an anti-ship missile. This missile is good, given its launched from 60m depth and sea skimming flight path, very close to surface of water. I was expecting YJ-18 for Hangors too. I suspect that YJ-18 might be procured as well in future. Different attack vectors with different angles & speeds will be death sentence for the enemy fleet.

*CM-708UNB* is the budget sub-launched workhorse. *YJ-18E* is the top-tier dual-speed killer. Different league.
Spec CM-708UNB YJ-18E
**Origin** CASIC, export version of C-802/C-803 CASIC, export version of YJ-18 (NATO: CH-SS-NX-13)
**Launch** Submarine torpedo tube only Ship VLS, submarine, coastal container
**Range** **290km** - capped for MTCR export **350km** export / 220-540km domestic
**Speed** All subsonic ~Mach 0.8-0.9 Subsonic cruise Mach 0.8, then **Mach 2.5-3.0 terminal sprint**
**Flight profile** Sea-skimming whole way Cruises low, then climbs, ejects booster and dives supersonic in last ~40km
**Warhead** ~155kg semi-armor piercing **140-300kg HE**
**Guidance** Inertial + satellite + radar seeker Beidou INS + datalink update + active radar
**Purpose** Hit medium/large ships, some land attack Anti-ship + land attack, designed to defeat Aegis
*Which is better? YJ-18E, by far:*

1. *Harder to stop:* A subsonic CM-708UNB can be shot down by modern CIWS / ESSM. YJ-18E's supersonic terminal dash + snake maneuver gives you <10 seconds to react.
2. *Longer range + bigger punch*
3. *More flexible:* YJ-18E can be VLS-launched from destroyers like Type 052D/055.

*Why CM-708UNB is still used then?*
Cost and export. It's MTCR-compliant and cheap. That's why Pakistan Navy just test-fired CM-708UNB from its new Hangor-class subs - YJ-18E is more expensive and China restricts it more closely.

If you had a choice for a modern navy: YJ-18E every time.
