Since the Aegis has demonstrated an ability to Shoot down low altitude satellites, is it possible to do so with these systems in Command?

That maneuvering by the RV was straight BS. An RV with an (I)IR seeker isn't going to be able to see and dodge SM-3s. It can maneuver, yes, but I'd assume that a light weight kill vehicle would be able to maneuver better than it.

Thanks for the info Sunburn, so if I have a scenario set up where for example I have Chinese satellites, and an Aegis BMD ship, how do I make it engage the satellite? What are the requirements in the sim for an attempt to happen against the satellite?

The SM-3 Block IA version provides an incremental upgrade to improve reliability and maintainability at a reduced cost. The SM-3 Block IB, due in 2010, offers upgrades which include an advanced two-color infrared seeker, and a 10-thruster solid throttling divert and attitude control system (TDACS/SDACS) on the kill vehicle to give it improved capability against maneuvering ballistic missiles or warheads. Solid TDACS is a joint Raytheon/Aerojet project, but Boeing supplies some components of the kinetic warhead. With Block IB and associated ship-based upgrades, the Navy gains the ability to defend against medium range missiles and some Intermediate Range Ballistic Missiles. SM-3 Block II will widen the missile body to 21 in and decrease the size of the maneuvering fins. It will still fit in Mk41 vertical launch systems, and the missile will be faster and have longer range. The SM-3 Block IIA will add a larger diameter kill vehicle that is more maneuverable, and carries another sensor/ discrimination upgrade. It’s currently scheduled to debut around 2015, whereupon the Navy will have a weapon that can engage some intercontinental ballistic missiles.[16]

The interception, at an altitude of 240km vividly demonstrated the ASAT capability of the U.S. Aegis sea based missile defense system. The intercept required only modification of the system software, and could have been done from any of the 5 cruisers or 16 destroyers equipped with the Aegis system at the time.

quote:

However, the latter phases of the PAA envision more capable Block II interceptors. Even using a conservative estimate of the burnout speed (4.5 km/s), SM-3 Block IIA interceptors would be able to reach the vast majority of satellites in low Earth orbit (LEO) (see Figure 1). Interceptors with burnout speeds at the high range of estimates for the SM-3 IIA (5.5 km/s) would be able to reach any satellite in LEO, as would the ground-based midcourse interceptors in Alaska and California.

Aegis BMD System8
Aegis ships are given a capability for conducting BMD operations by incorporating changes to
the Aegis system’s computers and software, and by arming the ships with BMD interceptor
missiles. In-service Aegis ships can be modified to become BMD-capable ships, and DDG-51s
procured in FY2010 and subsequent years are to be built from the start with a BMD capability.
Versions of Aegis BMD System
Currently fielded versions of the Aegis BMD system are called the 3.6.1 version and the newer
and more capable 4.0.1 and 4.0.2 versions. MDA and Navy plans call for fielding increasingly
capable versions in coming years; these planned versions are called 5.0, 5.0 CU (meaning
capability upgrade), and 5.1. Improved versions feature improved processors and software, and
are to be capable of using improved versions of the SM-3 interceptor missile (see Table 1).
Aegis BMD Interceptor Missiles
The BMD interceptor missiles used by Aegis ships are the Standard Missile-3 (SM-3) and the
Standard Missile-2 Block IV (SM-2 Block IV). The SM-2 Block IV is to be succeeded in coming
years by a BMD version of the new SM-6 interceptor.

quote:

MDA and Navy plans call for fielding increasingly capable versions of the SM-3 in coming years.
The current version, called the SM-3 Block IA, is now being supplemented by the more capable
SM-3 Block IB. These are to be followed by the even more capable SM-3 Block IIA.
Compared to the Block IA version, the Block IB version has an improved (two-color) target
seeker, an advanced signal processor, and an improved divert/attitude control system for adjusting
its course.
In contrast to the Block IA and 1B versions, which have a 21-inch-diameter booster stage at the
bottom but are 13.5 inches in diameter along the remainder of their lengths, the Block IIA version
is to have a 21-inch diameter along its entire length. The increase in diameter to a uniform 21
inches provides more room for rocket fuel, permitting the Block IIA version to have a burnout
velocity (a maximum velocity, reached at the time the propulsion stack burns out) that is greater
than that of the Block IA and IB versions,9
as well as a larger-diameter kinetic warhead. The
United States and Japan have cooperated in developing certain technologies for the Block IIA
version, with Japan funding a significant share of the effort.10
Until recently, a more capable missile called the SM-3 Block IIB was also planned. Compared to
the Block IIA, the Block IIB version was to include a lighter kill vehicle, flexible propulsion, and
upgraded fire control software.11 On March 15, 2013, however, the Department of Defense
(DOD) announced that it was
• “restructuring” (i.e., canceling) the SM-3 Block IIB program;
• shifting funding from SM-3 Block IIB program to other BMD efforts
(specifically, the Ground Based Interceptor (GBI) BMD program in Alaska and
to earlier versions of the SM-3); and
• dropping Phase IV of the European Phased Adaptive Approach (or EPAA—see
discussion below), which was to feature the deployment of the SM-3 Block IIB
missile.1

• Aegis Ashore in Poland with SM-3 IIA interceptors in the 2018 timeframe (Phase 3),
and
• SM-3 IIB interceptors and early intercept capability in the 2020 timeframe (Phase 4)
The United States will also pursue phased adaptive approaches in the Asia Pacific and the
Middle East by building on current efforts.13

• dropping Phase IV of the EPAA, which was to feature the deployment of the SM-
3 Block IIB missile.14
Each Aegis Ashore site in the EPAA is to include a structure housing an Aegis system similar to
the deckhouse on an Aegis ship and 24 SM-3 missiles launched from a re-locatable Vertical
Launch System (VLS) based on the VLS that is installed in Navy Aegis ships.
Although BMD-capable Aegis ships have deployed to European waters in the past, the first
BMD-capable Aegis ship officially deployed to European waters as part of the EPAA departed its
home port of Norfolk, VA, on March 7, 2011, for a deployment to the Mediterranean that lasted
several months.15

I wont get into exactly how fast a nuclear carrier can go, but, I will say, that when she's out in the deep blue and she's making flank you can water ski behind her, and she will eventually out run her escorts. 35+ knots without breaking a sweat.

Large-scale combat US operations were supported by the satellite system for the first time during the war with Iraq in 1990-1991. Despite the very long periods of operation of the satellites (some of the Chalet satellites had at that time been in orbit 11 or 12 years), at the time of the conflict they were put on a round-the clock schedule. The task of intercepting Iraqi radio conversations from space was made easier by the fact that they were for the most part using Soviet communications equipment of the sort the satellites had been designed against.

As a result of retargeting space-based SIGINT apparatus on the Iraqi radio nets, the volume of intercepted information significantly surpassed NSA's processing capability. Consequently the American command was forced to take urgent measures to increase the number of Arabic translators.

Along with carrying out the mission of strategic reconnaissance against Iraqi military C2 radio nets, the United States made special efforts to intercept information of tactical significance (e.g., the fact of airplanes taking off or the movement of tanks as revealed by the radio conversations of the crews) and to deliver it rapidly to users in the theater.

quote:

The missions carried out by space-based SIGINT systems expand as satellite hardware is modernized consist of the following:

- intercept and decryption of governmental, military and diplomatic communications transmitted by radio
intercept of ESM (RES) signals which characterize the operating modes of the higher command organizations, installations of air defense, ABM and missile forces, and also the combat readiness of foreign armed forces
reception of telemetry signals during ballistic missile tests
relay of radio messages from CIA agents in foreign countries.
According to data in the foreign press, the band of radio frequencies which can be intercepted by SIGINT satellites stretches from 100 MHz to 25 GHz. This, however, is difficult to realize in practice as there would have to be a collection of large-scale antennas of differing forms on a satellite. The satellites probably employ the widely used modular principle for combining equipment to carry out specific reconnaissance missions. This is indicated by the simultaneous deployment on orbit of several different groupings of SIGINT satellites (Rhyolite and Chalet, Vortex and Aquacade), which conduct reconnaissance in different parts of the radio spectrum.

WASHINGTON (Reuters) - The U.S. Air Force quietly has put into service a new weapon designed to jam enemy satellite communications, a significant step toward U.S. control of space.

The so-called Counter Communications System was declared operational late last month at Peterson Air Force Base in Colorado Springs, the Air Force Space Command said Friday in e-mailed replies to questions from Reuters.

The ground-based jammer uses electromagnetic radio frequency energy to knock out transmissions on a temporary and reversible basis, without frying components, the command said. "A reversible effect ensures that during the time of need, the adversary's space-based capability to threaten our forces is diminished," said Capt. Angie Blair, a spokeswoman. "Following the time of need, the space-based capabilities used by the adversary can return to its original state."

The device appears to have been put into service considerably earlier than had been projected by the Air Force as recently as February. At that time, a long-range planning document, dubbed the Transformation Flight Plan, said such a system would let the United States by 2010 "deny and disrupt an adversary's space-based communications and early warning" of attack. U.S. military control of space is one of four missions spelled out under a national space policy adopted by former president Bill Clinton in 1996.

The goal is to make sure U.S. forces have unhindered access to space and space-based services and to deny an enemy any similar benefits. The U.S. military has experimented with a range of "antisatellite" (ASAT) weapons, including lasers, to knock out enemy craft by destroying them or damaging their sensors.
