AMDR ships

AEGIS midcourse engagements routinely use one DDG to detect/track and another to shoo the SM-3, in this case 125 with it's SPY-6 was the former and 85 was the latter.

What is reason for this? Is it to test the data sharing between platforms as well as the radar? Is DDG-85 a non ABM vessel?

To test data-sharing. Because there are lots of engagement scenarios where the optimum geometry puts the sensor and the shooter in different places.

As a reminder, because I had to look it up: SPYU-6(v)4 is the 24-RMA retrofit version for the DDG-51 Mod 2.0 retrofit.

Reposting since it got lost in the forum Snap:
Raytheon/RTX is hoping to convince Japan to upgrade their existing DDGs using the v4. I haven't seen an official "JMSDF DDG 2.0" program mooted yet, but it seems pretty likely they're thinking about such an upgrade for the same reasons USN is doing it.

So, what were the options, SPY6 and SPY7? Any European options?

From the outset of the program, they were open to SeaFire and Kronos as well as the US radars. They signed onto the SPY6 program prior to this award and got FMS approval earlier this year, but Germany being Germany it wasn't certain they would stick with it
 
SPY-6 procurement schedule:

A brief overview of the SPY-6 variant mission requirements and array configuration is provided as follows:

  1. AN/SPY-6(V)1 is designed to meet mission performance and size, weight, and power – cooling (SWAP-C) requirements of the DDG-51 FLT III ships with AEGIS Baseline 10 (BL 10) combat system. The AN/SPY-6(V)1 will provide volume search, tracking, Ballistic Missile Defense (BMD) discrimination, and missile communications in a wide diversity of environments and conditions. This variant includes 37 Radar Modular Assemblies (RMAs) per array, each which contain independent transmit and receive LRUs and provide SPY +16 minimum sensitivity. There are 4 arrays per shipset.
  2. AN/SPY-6(V)2 is designed to meet Air Defense and Air Traffic Control mission performance and SWAP-C requirements of the CVN (Nimitz) class carriers, Landing Helicopter Assault (LHA) hulls, and Landing Platform/Dock (LPD) hulls. This variant includes a single array on a rotating platform, with 9 RMAs.
  3. AN/SPY-6(V)3 is designed to meet Air Defense and Air Traffic Control mission performance and size, weight, and power – cooling (SWAP-C) requirements of CVN (Ford) class carriers and will additionally provide engagement support for Future Frigate (FFG(X)) hulls. This variant includes 9 RMAs per array with 3 arrays per shipset.
  4. AN/SPY-6(V)4 is designed to meet mission performance and SWAP-C requirements of the DDG-51 FLT IIA ships with a variant of AEGIS Baseline 10 (BL 10) combat system, to be defined. The AN/SPY-6(V)4 will provide volume search, tracking, BMD discrimination, and missile communications in a wide diversity of environments and conditions. This variant includes 24 RMAs per array with 4 arrays per shipset.

The notional shipset procurement schedule (including potential FY27-30 FMS) for the above SPY-6 variants is:

SPY-6 VariantFY27FY27FY28FY29FY30FY31FY32FY33FY34FY35
AN/SPY-6(V)12–62–42–42–4222222
AN/SPY-6(V)20–21–60–50–1200100
AN/SPY-6(V)31–32–31–41211001
AN/SPY-6(V)422–52–32–3222222
Unit Totals5–137–185–166–9855545

Quantity Note: The Government is considering capturing potential FMS quantities in FY27-FY30 options on this future contract action, which drives the upper-range uncertainty. Multiple countries have expressed interest in procuring SPY-6 variants, but no formal FMS cases are in progress. There is potential for FMS quantities beyond FY30. USN quantities drive the lower end of the range and are stable through FY29, with increased potential for changes beyond.
