energy weapon. As used in the BMD program, brightness is the measure of
source intensity. To determine the amount of energy per unit area on a target,
both source brightness and source-target separation distance must be specified.
Brilliant Eyes
(BE)
OBSOLETE Successor to Space-Based Surveillance and Tracking System
(SSTS). BE is also known as the Space and Missile Tracking System (SMTS),
and is now the LEO element of the SBIRS. See SBIRS.
Brilliant Eyes
Probe (BEP)
OBSOLETE. The BE Probe is a concept for a ground launched probe version of
the BE space-based satellite, analogous to the obsolete GSTS, that would
leverage heavily the applicable BE Flight Demonstration System (FDS)
developed equipment. BEP could be developed and deployed on a shorter
schedule and could provide interim above-the- (radar) horizon threat tracking and
pre-commit for the interceptor. The concept requires the addition of non-FDS
LWIR sensor to a sub-set of the existing sensor complement, and is part of
potential Contingency Deployment Options. Also called the Ground Launched
Probe (GLP).
Brilliant Pebbles
(BP)
OBSOLETE. Proliferated singlet space-based weapon with autonomous
capability. (Now a subset of the Air Force’s Advanced Interceptor Technologies
(AIT) project.)

concept that is detailed in specific Phase Concepts of Operations.

Budget Activity (1) A budget activity is a major subdivision of a budget appropriation,
generally in mission areas. It records estimates for a component function
or activity to be funded by the appropriation. (2) Categories within each
appropriation and fund account that identify the purposes, projects, or
types of activities financed by the appropriation or fund.
Budget Authority Authority provided by law to enter into obligations, which generally result in
immediate or future disbursements of Government funds. It may be classified by
the period of availability, by the timing of congressional action or by the manner
of determining the amount available. Also known as Obligational Authority.
Budget Estimate Cost estimate prepared for inclusion in the DoD budget to support an acquisition
program.
Budget Estimate
Submit (BES)
The service submissions to OSD showing budget requirements for inclusion in
the DoD budget. Every other autumn (even years) for two-year budget, every
autumn of odd years for amendment to second year of previously submitted twoyear
budget.
Built-in Test
Equipment
(BITE)
Any device permanently mounted in the prime equipment and used for the
express purpose of testing the prime equipment, either independently or in
association with external test equipment.
Bulk Filter The signal processing rejection of detected signals as not being related to
objects of interest. The removal of sensor observations from the track files that
can be readily assessed by location or signature as non-threat (e.g., stars, boost
fragments, etc.).

BUR Bottom-Up Review.
Burden Costs not attributed or assigned to a system as a direct cost. Alternative term for

Burnout The point in time or in the missile trajectory when combustion of fuels in the
rocket engine is terminated by other than programmed cutoff.
Burn Rate The monthly rate at which a contractor’s funds are expended during the period
of the contract.
Burn-Through
Range
The distance at which specific radar can discern targets through the external
interference being received.
Bus The platform (or “bus”) sometimes referred to as a post-boost vehicle, on a single
missile, which carries all the warheads on that missile. May also carry penetration
aids, decoys, etc.
