[Hobbes]

Yes, go ahead.

 

[NMaude]

Yes, go ahead.

I'll have a look tomorrow however I might not have time to scan them as I'm going away on a two-week holiday with my family (Mum, aunt, siblings and their offspring) to Omanu beach (Just south of Mt. Mauganui).

 

[NMaude]

I've found the Raytheon brochures on the SM-2 Block-IVA however I won't have time to scan as I'm off for a two-week holiday in Omanu starting today.

 

[Hobbes]

No rush, have a good time there.

It seems like the Navy is sticking with the jet-tab TVC system for the SM-2IIIC. As some here might recall, the Navy was exploring a TVC design that featured SSSL in 2015. It seems to have been quietly given up on in favor of the original jet-tab design as discussed on the first page of this thread. The source of the screenshot is the latest 2022 DOT&E report.

This sounds more like what's used on ESSM in VLS systems, not something used to improve maneuverability.

Indeed, but ESSM used jet vane instead of a jet tab, USN researched several TVC mechanisms and down-selected three. Nonetheless, this still improves short-range performance.

 

[sferrin]

Awesome. I've never seen what the ejectable module on ESSM looks like. Jet TAB for Standard? That seems like an odd choice.

 

[NMaude]

Jet TAB for Standard? That seems like an odd choice.

Jet Tab would only be able to give pitch and yaw control whereas the jet-vanes (As used on the ESSM) would also give roll-control.

On another note does anyone have any performance figures for the Mk-72 booster such as its burn-time and thrust?

Are there available online any documents about the history and development of the Mk-72 booster introduced by the SM-2 Block-IV?

 

[sferrin]

How heavy is SM-6 without booster though?
could air launched version reach hypersonic?

About 2,600lb's...its a big boy...

I'm not buying that number, at all.

The SM6 all-up weight is around 3,300 pounds (official USN number). Of that, the Mk 72 is around 1,500 pounds (see attached brochure), leaving 1,800 pounds for the main stage. That's just about plausible; the maximum weight of an SM2 MR Block IIIB is usually quoted around 1725 pounds [Correction: 1558 pounds]. I can't see any way to get to 2600 pounds without a radical stretch that clearly has not happened here.

Could this be for the newer variant with the 21" missile body?

I saw a graphic once that indicated a burn out distance of 1800 feet. Not sure if there’s any truth in it.

[NMaude]

Snip.

Thanks.

Would the thrust of the Mk-72 be about the same as the previous Mk-70 booster?

 

[sferrin]

Mk 70 Booster (aka EX-70)

Manufacturer: Thiokol
Diameter: 0.46 meters
Length: 3.93 meters
Volume: 0.652 m3
Loaded Mass: 973 kg
Propellant Mass: 682 kg
Empty Mass: 291 kg
Propellant Type: HTPB-AP
Propellant ISP: 260 to 265 seconds

Mk 72 Booster

Manufacturer: Aerojet
Diameter: 0.53m
Length: 1.70m
Volume: 0.374 m3
Loaded Mass: 712 kg
Propellant Mass: 468 kg
Empty Mass: 244 kg
Propellant Type: HTPB-AP
Propellant ISP: 260 to 265 seconds
Burn Length: 6 seconds

Notes: A significantly shorter booster developed to enable SM-2ER to be fired from AEGIS VLS.

The Mk70 is burning about 50% more fuel in roughly the same amount of time so I'd say no.

 

[NMaude]

I've just been doing some google searching on the Mk-72's thrust and I found this paper, Parameter Estimation and Analysis of Standard-2 Missile, which if accurate states that the thrust of the Mk-72 is 174KN or 39,150Lbf.

From the figures I posted above it would give about 44,700lb of thrust at the low end. The ISP your source gives for the booster is quite low (224 ISP).

 

[NMaude]

That's a good point.

The ISP your source gives for the booster is quite low (224 ISP).

Good point, however I'd say that the scientist writing that paper were using estimates based on publicly available data which appears to be rather sparse.

Edited to add: Thinking about those Isp figures the Chinese researchers used in their paper may be typical of equivalent solid rocket-motors used by the PLA.

 

[NMaude]

I was at the library today (I don't have a scanner at home) and I scanned a 1997 Raytheon brochure for the SM2 Block-IVA missile, here it is:

 

[CIC-TAO]

MDA with Navy July 24 tested SM-6 Dual II, fired four from Burke destroyer Ralph Johnson off Hawaii, presuming to test if effective in defending a carrier against the Chinese anti-carrier ballistic missiles DF-21 and 26

" one target was successfully intercepted. At this time, we cannot confirm the second target was destroyed"

Anyone know the difference between the SM-6 Dual I and Dual II?

From <https://www.mda.mil/news/21news0012.html>

Would Dual II use the new 21” body?

No, the 21-inch version is SM-6 Block 1B. SM-6 Dual II seems to be a simple upgrade of the Dual I version, which enabled both air and missile defense in a single missile.

SBT increment 2

 

[CIC-TAO]

这里有一张有趣的图表，显示了美国海军库存中各种主要舰载导弹的潜在目标。

对我来说，这里出乎意料的启示是，带有 21 英寸推进堆栈的新版本 SM-6 Block 1B 被显示为严格的 ASuW 武器。也许只是教义问题？（SM-6 Blk IA 将在 AAW 角色中做所有必要的事情）

编辑：看来我欠这个 PowerPoint 操作员一个道歉：https://www.secretprojects.co.uk/threads/standard-missile-projects.7671/page-4#post-343886

（较小的启示是，他们不认为 RAM 或 ESSM 具有 ASuW 能力，尽管 HAS 自 1990 年代末以来就已经存在。也可能是一种理论而非技术选择。）

FY24 ten SM-6 IB, unit cost 8.54M

 

[sferrin]

Jesus.

 

[Josh_TN]

Presumably these are pre-production/LRIP rounds. I wouldn't have thought IB would be twice as expensive as IA when the main change is a larger rocket.

 

[bring_it_on]

We also know that it has a newer warhead and probably other changes that have not been publicly disclosed.

I had thought that SM-6 Ib used the necked down to the same front end as SM-Ia?

Yes. I thought the IB uses the existing warhead and guidance of the IA, just with a 21” motor.

MDA Test Successfully Intercepts Ballistic Missile Target

PACIFIC OCEAN - The U.S. Missile Defense Agency, in cooperation with the U.S. Navy, successfully conducted Flight Test Aegis Weapon System 31 Event 1a (FTM-31 E1a).

www.cpf.navy.mil

A Standard Missile-6 (SM-6) Dual II with Software Upgrade (SWUP) is launched from the USS Daniel Inouye (DDG 118) off the coast of the Pacific Missile Range Facility in Kauai, Hawaii as part of Flight Test Aegis Weapon System 31 Event 1a (FTM-31 E1a), March 30, 2023. The Missile Defense Agency, in cooperation with the U. S. Navy, held the successful missile defense event that demonstrated the capability of a ballistic missile defense (BMD)-configured Aegis ship to detect, track, engage, and intercept a medium range ballistic missile target in the terminal phase of flight utilizing the SM-6 Dual II SWUP in a single salvo of two interceptors.

Does anyone know what the MRBM target was?

strange , I think FTM-31 E1a include 4 SM-6 attack 2 targets

I scanned three more STANDARD missile brochures that I'd got from Raytheon in 1998. and 1999 today:

Says two and one target. Maybe 4 + 2 was too expensive.

Yes , Only medium range ballistic missile target in press , but maybe another is a cruise missile target or Hypersonic traget . I hear T3C2 traget is interesting . seems like there are different RVs . one of they is a Hypersonic traget .
