VanHerck highlights at #smdsymposium 2021:
-Defining integrated deterrence: “Deterrence is created every day using all levers of influence”
-To disrupt US power projection, peer adversaries are “clearly focused on [striking] the homeland…It’s in their doctrine”
-China recently demonstrated “very advanced” hypersonic glide systems, says will not go into further detail
-Missile Defense and Nuclear Posture Reviews “cannot be separate”
-“It’s unrealistic and unaffordable to think we can defend everything”
-Homeland defense should move further left and “into the information space” at the level of competition
Bottom lines:
-Rebalance strategy, budgets from overwhelming focus on kinetic conflict to other levers more useful for competition
-Peer adversaries have the capability and intent to strike homeland to deny US power projection/forward posture
-Kinetic attacks will happen under nuclear threshold, nonkinetic attacks under conflict threshold

VCJCS Hyten speaking at #SMDC2020:
"I wanna give the Army a little bit of a hard time...the Space and Missile Defense Command [name]—it's schizophrenic"
"Space is a place, missile defense is a mission."
Knowing laughter as Hyten discusses naming confusion with AAMDC.
Hyten: Joint fires, contested logistics, joint c2, information advantage are "supporting concepts" needed by joint force, recently signed strategic directive for services to build requirements.
Hyten: discusses service input/analysis of Joint Requirements Oversight Council process. Critiques "slow, moribund" DoD requirements bureaucracy. Points to Schriever and Minuteman, Rickover and sea-based deterrent as architects of DoD institutional change.

#SMD2021 panel: RCCTO internally referred to LRHW as Army's "dark eagle." No difference in 34.5" booster for Army and Navy systems, except canister. TEL is built off existing trailer, and "took a known C2 system" for battery operations. Image
BG Rafferty: "we're going to have an application on the Titan ground station that is going to generate the calls for fire"— ML model will be "driven by the commander's high priority target list"
"The materiel domain is leading…and pulling the other domains along. And I think that’s the reality of the Information Age, of the 21st century—is that technology is going to lead us. And it’s one of the fundamentals of the Army Futures Command approach, which is...

Intercept photos of South Korea's Haegung shipborne air defense missile. One of the few non-US systems to incorporate both a radar and IR seeker.

PC: ROK ADD
South Korea's Agency for Defense Development publishes quite detailed photos, video, and diagrams of their surface-to-air systems in particular. (Pictured: M-SAM-I and M-SAM-II)
More M-SAM intercepts and schematic.

Thread on Russian missile defense countermeasures I couldn't find a home for. According to V.C. Belous, Soviet design bureaus began development of balloon decoys and dipole chaff in the early 1960s; projects dubbed "Willow," "Cactus," and "Mole."

(Belous 2002)
It's hard to find which entities were involved, but the Central Research Radiotechnical Institute (CNIRTI) was the only one I found explicitly named. They reportedly developed varieties of chaff, decoys, jammers, and other devices since the 1950s.

(Spassky et al 2004)
Between 1960 and 1970, the Corporation of Research and Development establishments and other entities developed 9 decoy systems, named "List," "Pa'lma," "Ledokol," "Kiparis," "Bereza," "Kashtan," "Magnolia," "Lavr," and "Vyaz."

The Navy originally contemplated a variety of THAAD variants for its theater missile defense system before settling on the SM-3 design.

Something I haven't seen much of was the SM-2 block IVA.

The Block IVA, and THAAD, were some of the few interceptors designed with IR seekers for interception within the atmosphere.

Dr. Gillian Bussey reveals ongoing work on HyFly 2 airbreathing hypersonic weapon at IDGA Hypersonic Summit. Intended for use on carrier-based aircraft. Original HyFly program ended w/ unsuccessful flights in 2006, 2007. HyFly 2 completed Critical Design Review in the last year.
HyFly uses a Dual Combustion Ramjet, a hydrocarbon propulsion tech developed by JHU APL in 70s/80s and matured through HWT and ARRMD programs. Uses 2 sets of scoops & combustors for supersonic and subsonic combustion, allowing for performance over wider speed range up to Mach 6.
The Navy successfully tested a 50%-scale HyFly engine, FASTT, in 2005.
