The Nation's annual support for development has changed little since the mid 1980s. From 1980 to 1985 development grew on average by 6.8 percent per year in real terms as increasingly larger shares
of the national R&D effort were directed toward defense R&D, which is 90 percent development. Between 1986 and 1994 the estimated average annual real growth rate subsequently fell to less than 1 percent, climbing from $78 billion to $83 billion
(constant 1987 dollars) before settling back to $80 billion in 1994. Growth in both industry's and the Federal Government's development support slowed considerably, the latter reflecting the fiscal constraints placed on overall defense spending. Of
1994 national spending on development, industry provided 70 percent of the total and the Federal Government, 29 percent.
In terms of performance, industry is estimated to have accounted for 85 percent ($86 billion) of the Nation's 1994 development activities. Federal intramural activities account for practically all
($10 billion, or 9 percent of total) of the rest.
