(for example, solid core, liquid core, gas core fission);
 (iv) plasma based propulsion systems;
 (12) thrusters (for example, rocket engines) that provide greater than 150 lbf (that is, 667.23 N) vacuum thrust (MT for rocket motors or engines having a total impulse capacity equal to or greater than 8.41x10^5 newton seconds);
 (13) control moment gyroscope (CMG) specially designed for spacecraft;
 (14) space‑qualified monolithic microwave integrated circuits (MMIC) that combine transmit and receive (T/R) functions on a single die as follows:
 (i) having a power amplifier with maximum saturated peak output power (in watts), Psat, greater than 200 divided by the maximum operating frequency (in GHz) squared [Psat >200 W*GHz2/fGHz2];
 (ii) having a common path (for example, phase shifter‑digital attenuator) circuit with greater than 3 bits phase shifting at operating frequencies 10 GHz or below, or greater than 4 bits phase shifting at operating frequencies above 10 GHz;
 (15) space‑qualified oscillator for radar in paragraph (a) of this category with phase noise less than −120 dBc/Hz + (20 log10(RF) (in GHz)) measured at 2 KHz*RF (in GHz) from carrier;
 (16) space‑qualified star tracker or star sensor with angular accuracy less than or equal to 1 arcsec (1‑Sigma) per star coordinate, and a tracking rate equal to or greater than 3.0 deg/sec, and specially designed parts and components therefore (MT);
 (17) primary, secondary or hosted payload that performs any of the functions described in paragraph (a);
 (18) secondary or hosted payload, and specially designed parts and components therefor, developed with US Government funding;
 (19) spacecraft heat shields or heat sinks specially designed for atmospheric entry or re‑entry, and specially designed parts and components therefor (MT if usable in rockets, SLVs, missiles, drones or UAVs capable of delivering a payload of at least 500 kg to a range of at least 300 km);
 (20) equipment modules, stages, or compartments that contain propulsion other than that required for attitude control and can be separated or jettisoned from another spacecraft (see note 2 to paragraph (a));
 (21) any part, component, accessory, attachment, equipment, or system that:
 (i) is classified; or
 (ii) contains classified software; or
 (iii) is being developed using classified information.
Note 1: For the purposes of this paragraph, an article is space‑qualified if it is designed, manufactured, or qualified through successful testing, for operation at altitudes greater than 100 km above the surface of the Earth. The use of an altitude of 100 km above the surface of the Earth in this paragraph does not represent a legal demarcation between national air space and outer space under United States or international law.
Note 2: (1) A determination that a specific article (or commodity) (for example, by product serial number) is space‑qualified by virtue
