I wonder if there're any details available about exactly what sort of hardware changes there are?
I guess everything thats different between sm-6 Block 1a and SM-2 Block 3C guidance.I wonder if there're any details available about exactly what sort of hardware changes there are?
Would you elaborate please?I guess everything thats different between sm-6 Block 1a and SM-2 Block 3C.
Now the only thing i think of that would be new is the GPS. But we can't forget that many things could obsolet so they just Switch the whole model.Would you elaborate please?
Tangentially related example: The primary flight control computers in the F-22 are 386s. Two generations before Pentiums first came out...Would you elaborate please?
A question about RIM-2 Terrier. Have its nuclear-tipped version the ability to strike land targets? The nuclear-tipped Talos have such capability, but I'm not sure about Terrier.
ISTR in Friedman's cruiser book it was mentioned that in the mid to late '50s guns (other than perhaps the 3" 70) were seen as being redundant in the future because Terrier with a nuclear warhead could do all necessary shore bombardment such as area effect, defoliating, and dealing with hardened targets (that pillbox is GONE!). 3 inch guns were considered completely adequate for anything else a gun was needed for and were thought to be effective close in weapons. So I imagine it was at least considered.A question about RIM-2 Terrier. Have its nuclear-tipped version the ability to strike land targets?

The only nuclear version, BT-3A(N), was still a beam-rider, so it should go wherever it was pointed.

I ran across some mention of a nuclear Talos on probably the okieboat website (USS Oklahoma City, and now I'm not finding this story on that site...), they were in the Med and being harassed by Libyans at the time. Junior weapons officer asked the guys if they could work out a surface strike on one of the harassing air bases. The enlisted say sure, we'll need to dig into the books to set it up right, so give us a bit.I found mentions about nuclear Terrier having coastal-strike capability in some early 1960s Navy hearing in Congress, so it seems that it was at least theoretically possible. No mention about how it was done, but I assume that the same method as with nuclear-tipped Talos was used (special computer calculated the target position, missile rode the beam and over target was sent to dive, then a detonation command was transmitted). After all, Terrier and Talos shared the main principles of beam-riding guidance.
Hm. It can't be USS Oklahoma City; as far as I knew, she never were in Mediterranean during all her career. Most likely it could be "Little Rock", she served in Med most of her career.I ran across some mention of a nuclear Talos on probably the okieboat website (USS Oklahoma City, and now I'm not finding this story on that site...), they were in the Med and being harassed by Libyans at the time.

Theoretically doable, but I suspect on practice it would require too many safety measures be circumvented.So they come back to brief the junior officer about the plan, and that air base is a bit outside the missile's official range, and that there's a mountain between the base and the ocean. They'd planned it out so that the missile would be out of fuel and gliding as it was directly overhead the offending airbase, where it'd drop out of the guide beam. They mention that while the missile is beam-riding, that's not an issue since the nuclear warhead would detonate if the missile ever left the guidance beam, and that's where they want it to detonate anyways.
Could be. Now I'm annoyed that I didn't save that website.Hm. It can't be USS Oklahoma City; as far as I knew, she never were in Mediterranean during all her career. Most likely it could be "Little Rock", she served in Med most of her career.
Apparently the thing about the warhead detonating if the missile ever left the guidance beam was part of the positive control that was required at the time. If the missile left the guidance beam it was no longer under control of the guidance system, so it was seen as better to detonate the warhead and maybe have it still close enough to be effective than to drop an armed nuke out of the sky.Theoretically doable, but I suspect on practice it would require too many safety measures be circumvented.
I knew that losing the beam was self-destruct command, butI always thought that for nuclear warhead a specific detonation command needed to be issued?Apparently the thing about the warhead detonating if the missile ever left the guidance beam was part of the positive control that was required at the time.

From what I remember of this story, it was not.I knew that losing the beam was self-destruct command, butI always thought that for nuclear warhead a specific detonation command needed to be issued?

Yep. It also have self-destruct in case of signal loss, but as far as I knew, self-destruct was not nuclear.The MIM-14 Nike Hercules required a specific command signal to detonate its' warhead for example

Some sources mention that later beam-rider Terrier's (BT-3A models, with tail control and extended range) could be used in anti-ship mode.
Mostly because nuclear warheads for SAM's weren't viewed as good solution anymore. There were two main reasons:On another note why did the US Congress cancelled production of the W81 warhead as the Standard missile equipped with the warhead would've replaced the obsolete RIM-2D and its' W45 warhead?
By subjecting the enemy atomic bomb to intence neutron flux from nuclear SAM detonation, they could be "poisoned" by creation of short-lived isotopes in their nuclea fuel. If such "poisoned" bomb would try to detonate, it would just fizzle.
About that I'm not sure; I suspect that it would require such intense irradiation, that plane and bomb would be destroyed anyway.Not just the creation of short-lived radio-isotopes but that neutron-flux would also heat up the plutonium causing it to slump and deform.

Wow, I bet there were some people looking shifty during decommissioning.IIRC enhanced Neutron Flux was the reason why the weapons inside SPRINT and SPARTAN were literally gold plated.

- US Navy warships fired SM-3s to intercept Iranian ballistic missiles last weekend.
- Secretary of the Navy Carlos Del Toro confirmed the use of the SM-3 during a Tuesday hearing.
- It's the first time that the exo-atmospheric interceptor has been used in combat.
US Navy warships used a missile interceptor for the first time in combat over the weekend while defending Israel from an unprecedented Iranian attack.
Secretary of the Navy Carlos Del Toro said American forces fired the Standard Missile 3, or SM-3, to engage Iranian ballistic missiles that were fired as part of the massive barrage, which included more than 300 missiles and drones launched from Tehran and its proxies.
"We've been firing SM-2s, we've been firing SM-6s, and just over the weekend, SM-3s, to actually counter the ballistic missile threat that's come from Iran," Del Toro said at a Senate Appropriations Subcommittee on Defense hearing on Tuesday.
The first use of the SM-3 in combat occurred during the 2024 Iranian strikes in Israel. USS Carney and USS Arleigh Burke used four to seven missiles[49] to shoot down at least six Iranian ballistic missiles.[50]
Do they still use IAs?As far as I know there's no indication whether the SM-3s fired were Block-IBs or Block-IIs

My guess would be Block 1Bs, not Block 2A. older and less capable, but also more easily replaced because the rockets are older.As far as I know there's no indication whether the SM-3s fired were Block-IBs or Block-IIs

I'd be surprised if there are any in the theater. Is it even done with testing? Pretty sure they only have a handful at this point.Good points BUT I could see at least one Block-2A being firing just to see how it performs in an actual combat situation, a trial by fire.

On 16 November 2022, the guided-missile destroyer Maya fired an SM-3 Block IIA missile, successfully intercepting the target outside the atmosphere in the first launch of the missile from a Japanese warship.
