BALTIMORE, DEC. 21 -- A former officer and a former consultant of a Silver Spring defense contractor pleaded guilty today to a four-year-long scheme to bribe a Navy official to steer millions of dollars in computer-related contracts their way.

Clarence Braddock, 61, of Alexandria, one-time president and chief executive officer of Automated Sciences Group (ASG), and Louis J. Rainey, 61, of Ocean City, an independent defense consultant, admitted in federal court they paid thousands of dollars in bribes to Richard D. Ramirez, former minority small business coordinator for the Navy and a key figure in the Wedtech procurement scandal of the 1980s.

Braddock and Rainey each face up to five years in prison and $250,000 in fines.

A sentencing date was not set, and the two remained free on personal bond.

Both are now cooperating with prosecutors in an investigation of ASG, a black-owned firm that designs office automation and computer software for warehouses.

ASG and its former chairman, Conrad Hipkins, 58, of Silver Spring, were indicted earlier this month on charges similar to those against Braddock and Rainey.

Hipkins and the company have denied guilt and are scheduled for trial March 18.

Prosecutors heading the probe by the FBI and Defense Criminal Investigative Service said ASG and its former officers paid Ramirez $103,000 in bribes from 1983 to 1987.

In that period, ASG won three contracts totaling $8 million, including one to develop software and other support services for the Navy's Trident submarine-launched missile system.

Ramirez pleaded guilty to receiving $180,000 in bribes from Wedtech and another defense contractor, United Chem Con, in the 1980s.

He is serving a one-year prison sentence.

ASG attorney Bruce A. Baird said current officers of the firm are not involved in the bribery allegations.
