https://en.wikipedia.org/wiki/Aegis_Combat_System

Ballistic Missile Defense[edit]
The Aegis Ballistic Missile Defense System (BMD) program by the U.S. Missile Defense Agency enables the Aegis system to act in a sea-based ballistic missile defense function, to counter short- and medium-range ballistic missiles of the variety typically employed by a number of potential opponent states. The program is part of the United States national missile defense strategy and NATO European missile defense system.[1]
BMD capabilities allow vessels equipped with Mk 41 Vertical Launching System (VLS) to intercept ballistic missiles in post-boost phase and prior to reentry, using the RIM-161 Standard Missile 3 (SM-3) mid-course interceptors[13] and the RIM-156 Standard Missile 2 Extended Range Block IV (SM-2ER Block IV)[14] terminal-phase interceptors.[15] The SM-2ER Block IV can engage the ballistic missiles within the atmosphere (i.e. endoatmospheric intercept) in the terminal phase of a missile's trajectory with a blast fragmentation warhead. The Standard Missile 3 is a development of the SM2-ER Block IV, capable of exo-atmospheric intercept (i.e. above the atmosphere) during the midcourse phase; its kinetic warhead (KW) is designed to destroy a ballistic missile's warhead by colliding with it. RIM-174 Standard ERAM (Standard Missile 6) extended range active missile is a further development of the SM-2ER Block IV, which adds a booster and an active radar homing seeker.[16] SM-6 can be used for either air defense or ballistic missile defense, providing extended range and increased firepower; it is not intended to replace the SM-2 series of missiles.[17] The SM-6 Block IB includes a larger 21-inch rocket motor that sits on top of the 21-inch booster.[18]
To enable Ballistic Missile Defense capabilities, signal processing for the SPY-1 radar was upgraded using commercial off-the-shelf components and open architecture standards.[19] The Multi-Mission Signal Processor (MMSP) provides Anti-Air Warfare (AAW) and Ballistic Missile Defense (BMD) capability for the first 28 ships (DDGs 51–78) of the U.S. Navy's Arleigh Burke-class destroyers. This capability is also incorporated in USS John Finn (DDG-113) and following new construction, as well as Aegis Ashore. MMSP modifies transmitters of the SPY-1D radar to enable dual-beam operation for reduced frame times and better reaction time, and provides stability for all waveforms, allowing the radar system to detect, track, and support engagements of a broader range of threats. MMSP improves performance in littoral, ducted clutter, electronic attack (EA), and chaff environments and provides greater commonality in computer programs and equipment.[20][21]
As of April 2022, the U.S. and Japan are the only countries to purchase or deploy the Aegis BMD on their military ships.[22][23][24]
Flight III of Arleigh Burke class destroyers starting with USS Jack H. Lucas (DDG-125) are equipped with AN/SPY-6 AESA radar from Raytheon, which is 30 times more sensitive and thus can handle 30 times more targets comparing to the SPY-1D radar, providing increased air and missile defense capabilities.[25][26] Flight IIA ships will also be upgraded to SPY-6 in the future, giving them Aegis BMD capabilities.[26][25]
Aegis Ashore is a land-based version of Aegis BMD which includes the AN/SPY-1 radar and command systems, and Mk 41 VLS equipped SM-3 and SM-6 missiles. Test installation exists at the Pacific Missile Range Facility in Hawaii. A site in Deveselu, Romania is operational since 2016, and a site near Redzikowo, Poland will become operational in 2022. Japan intended to deploy two systems with an AN/SPY-7 AESA radar by 2021, but cancelled these plans in 2020. Possible deployments of Aegis Ashore include U.S. naval base at Guam.[22]
U.S. Army Integrated Air and Missile Defense Battle Command System (IBCS) program aims to integrate Aegis BMD and its AN/SPY-1 and AN/SPY-6 radars with MIM-104 Patriot (AN/MPQ-65A and GhostEye), NASAMS (GhostEye MR), AN/TPY-2 (THAAD and GMD), and F-35 Lightning II (AN/APG-81) radars to form a plug and fight network of land, sea, and air-based sensors to help detect and track ballistic missile threats and select Patriot and THAAD surface-to-air launchers that are best positioned for a successful intercept.

Glad to know we have something to counter.

Yeah it was pretty awesome.  I've never seen anything like it, and it's highly likely I never will again.

For people who have only seen partial eclipses, or even saw as much as 99% yesterday but not totality, all I can say is-- it's a completely different experience.  There's just no way to compare it to anything else, unless I suppose you're an astronaut.

The clouds were patchy during the leadup, but we got lucky and got a cloud break through almost the entirety of totality. 

I also recommend, would see again.
I am jealous. Have never seen a total eclipse in person.   Can only imagine from photos how cool it is.   I did go look at it here in Florida, and even though it was roughly a half eclipse, it was still pretty cool to see it

We saw about a 94% eclipse here around Houston.  You're right, it really wasn't impressive.  I would have like to see the full eclipse in person, but it just wasn't in the cards yet.  Maybe next time.....in another part of the world.

Yeah I've seen several partial eclipses, and they're been interesting.  I doubt I'd ever travel to see another partial but if one comes to my location I'll certainly go outside and look at it.  Especially now that I have several pair of eclipse glasses!

Now, for a total eclipse-- I might be tempted to travel for one again.

Bear in mind the warhead from any ICBM will be without communication during reentry due to friction.  And you’d need to hit within a hundred meters or so to damage a carrier without a nuke.

and almost all nuclear missiles from our enemies would be outdated older models

not sure how easy it would be to upgrade those things

war heads interchangeable?

I'd be 78. She'd be 83.

Weird to think about this.

My fraternity brother (fellow EE, who used to live down here in San Diego) who is a day older than me already sent my wife and I calendar invites for 2043 when we both turn 65 for a French wine tasting trip to kick off our retirements. 

Gonna have to start planning that, I guess :57:

I would have started at 62, but you're probably making too much money.

Forget all that, there's going to be two in a row that hit Spain in 2026 and 2027.  Easy peasy!
