BID Built-In Diagnostics.
BIDS Biological Integrated Detection System.
Biennial Budget The FY86 DoD Authorization Act required the submission of two-year budgets for
the Department of Defense beginning with FY88/89. The department has
institutionalized a biennial cycle for the Planning, Programming, and Budget
System (PPBS). A biennial budget, as currently structured, represents program
budget estimates for a two-year period in which fiscal year requirements remain
separate and distinct.
Big Crow A suite of aircraft, helicopters, ground vans, and electronic equipment, which is
used to emulate an electronic warfare environment for testing, weapon systems
on test ranges.
BIM Ballistic Intercept Missile.
Biological
Weapon
An item of material, which projects, disperses, or disseminates a biological agent
including arthropod vectors.
BIOS Basic Input/Output System.
BIPS Billion Instructions Per Second.
Birth-to-Death
Tracking (BDT)
The tracking of space objects (e.g., satellites, reentry vehicles, or decoys that
simulate these) from the time they are deployed from a booster or post-boost
vehicle until they are destroyed.
Bistatic Radar A radar system that has transmitters and receivers stationed at two
geographically separate locations; a special case of multi-static radar.
BIT Built-in-Test
Bit Binary digit.
BITE Built-in Test Equipment.
Bit Transfer
Rate
The number of bits transferred per unit time, usually expressed in bits per second
(bps).
Black Body An ideal body, which would absorb all (and reflect none) of the radiation falling
upon it.
Blackout The disabling of electronic equipment by means of nuclear explosion. The
intense electromagnetic energy by a nuclear explosion obscures signals and
renders many types of radar and other types of electronic equipment useless for
minutes or longer.
BLADES BMD Long Wavelength Infrared Advanced Exo-atmospheric Sensor.
BLADT Blast, Dust, Thermal Effects Model.
Blast Effect Destruction of or damage to structures and personnel by the force of an
explosion on or above the surface of the ground. Blast effect may be contrasted
with the cratering and ground-shock effects of a projectile or charge that goes off
beneath the surface.

Blast Wave A sharply defined wave of increased pressure rapidly propagated through a
surrounding medium from a center of detonation or similar disturbance.
BLCCE BMDO Life Cycle Cost Estimate.
BLK Block (system production lot)
Blk IVA Navy Standard Missile Block IV-A.
Block (1) A biennial increment of the Ballistic Missile Defense System that provides an
integrated set of capabilities which has been rigorously tested as part of the
BMDS Test-bed and assessed to adequately characterize its military utility. Once
tested, elements and components are available for limited procurement,
transition to production, or for emergency deployment as directed. These “offramps”
may occur at any time during the Block Cycle to support timely execution
of these transition or deployment decisions.
The configuration for each Block is drawn from the following sources:
• The prior BMDS Block;
• BMDS elements, components, technologies, and concepts;
• BMDS Battle Management, Command, Control, and Communications
(BMC2/C) specifications and products;
• Externally managed systems, elements, or technologies (e.g., DSP,
GCCS, MILSTAR, etc).
Each successive Block provides increasing levels of capability to counter Ballistic
Missiles of all ranges and complexity. (MDA Lexicon)
(2) This term is used to designate a portion of a multi-message packet that is
dedicated to a message contained within the packet.
Block Check
Character (BCC)
The result of a transmission verification algorithm accumulated over a
transmission block, and normally appended at the end, e.g., CRC, LRC.
