The Drive had a piece on SSTDs that was pretty good, and gave an idea as to the extent it has reached the fleet.

believe there is another EM TD but has since been taken off the internet.

Ok, pretty sci fi, but the future is now. These are really not that new of ideas. The idea of a Semi submersible large combatant has been around for long time and people are tired of talking about arsenal ships but they are still talked about because they are still relevant.   not considering such now maybe an unaffordable oversight. (just replace the VLS w/ Vertical guns  :)

Idea or attempt is good, however balance between cost and effectiveness should be carefully considered.

Sealing for submersible vehicle is not cheap task for big ship (radar, external guns, antenna, hanger for helo)

yes, huge issues and most likely only semi-submers even makes sense and they would big big cost for sure.  The alternative though is maintain a staid maritime manufacturing culture which loses.

Still don't know why this wasn't in last year, but nice to see it now.

The Navy is developing three new ship-based weapons that could improve the ability of Navy surface ships to defend themselves against missiles, unmanned aerial vehicles (UAVs), and surface craft: the Surface Navy Laser Weapon System (SNLWS), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), previously known as the hypervelocity projectile (HVP).

The Navy refers to the initial (i.e., Increment 1) version of SNLWS as HELIOS, an acronym meaning high-energy laser with integrated optical dazzler and surveillance. EMRG could additionally provide the Navy with a new naval surface fire support (NSFS) weapon for attacking land targets in support of Marines or other friendly ground forces ashore. The Department of Defense is exploring the potential for using GLGP across multiple U.S. military services.

WASHINGTON — The U.S. Defense Department is planning to increase investments in directed-energy systems used for missile defense over the next several budget cycles, according to the department’s top technology adviser.

Michael Griffin, undersecretary of defense for research and engineering, said Tuesday he expects to have usable directed-energy weaponry in the hands of war fighters in “no more than a few years,” but acknowledged the size of a system usable for missile defense requires greater investment.

“You need another factor of three to four to have as space control weapon, a missile defense capability — space-based, boost-phase or midcourse capability — with a large directed-energy weapon. We need to be in the megawatt class to have that,” Griffin said at an event hosted by the Center for Strategic and International Studies.

A couple details from the latest Report to Congress on the Aegis system.

SM-6

"A July 23, 2018, press report states:
The Defense Department has launched a prototype project that aims to dramatically
increase the speed and range of the Navy's Standard Missile-6 by adding a larger rocket
motor to the ship-launched weapon, a move that aims to improve both the offensive and
defensive reach of the Raytheon-built system.

On Jan. 17, the Navy approved plans to develop a Dual Thrust Rocket Motor with a 21-
inch diameter for the SM-6, which is currently fielded with a 13.5-inch propulsion package.
The new rocket motor would sit atop the current 21-inch booster, producing a new variant
of the missile: the SM-6 Block IB
.9"


SM-3 Block IIA

"A March 26, 2018, press report states the following:
[MDA] Director Lt. Gen. Sam Greaves said MDA “is evaluating the technical feasibility
of the capability of the SM-3 Block IIA missile, currently under development, against an
ICBM-class target.”

“If proven to be effective against an ICBM, this missile could add a layer of protection,
augmenting the currently deployed GMD system,” Greaves said in written testimony
submitted March 22 to the Senate Armed Services strategic forces subcommittee.
[Greaves] said MDA will conduct a demonstration of the SM-3 Block IIA against an
ICBM-like target by the end of 2020...."

If your going to spend the money to chase "ICBM class target" better design it against hypersonics as well.

Why would you think it would cost additional money to hit ICBMs?  They're testing to see if the Block IIA ALREADY has the capability.  They're not making a Block IIB to "chase ICBMS".   And an exoatomospheric ICBM RV compared to an endoatmospheric, winged, maneuvering vehicles is apples and oranges.

Yeah and the SM3 already intercepts hypersonic missiles in the mid-course phase. As Mike Griffin described boost glide defense, it is really a capability aimed at intercepting very fast cruisers at altitudes ranging from 30-60km. SM3 isn't going to do that and I doubt SM6 will either. Perhaps a common Army-Navy interceptor to cover this capability gap is the way forward.
