sites, have been struck during 1965, 1966, and
 January-August 1967 by about 9,700 attack sorties
 delivering more than 15,700 tons of ordnance.
 Attacks against railroads during 1967 alone amounted
 to more than 10,100 attack sorties delivering almost
 21,200 tons of ordnance.

B. The Effects of the Bombing - Economic and
 Military Damage

Although the Rolling Thunder program is
 preponderantly an interdiction effort against transportation
 routes and other logistic targets, attacks
 against major industrial plants and important
 military targets have given new dimensions to the air
 war.

The 1967 campaign against important industrial
 facilities has brought North Vietnam's small modern
 industry to a standstill. About 80 percent of the
 central electric power generating capacity is
 currently out of operation. All the central generating
 plants in the main Hanoi-Haiphong network,
 with the exception of the main Hanoi plant itself,
 have been out of service since early June.

The country's only modern cement plant -- at
 Haiphong -- ceased production in April 1967 because
 of bomb damage and the loss of its electric power
 supply. The country's only metallurgical plant --
 at Thai Nguyen -- which produced pig iron for export
 and fabricated products from imported steel has
 ceased production for the same reasons. The only
 explosives plant has been out of operation for two
 years, and the production of apatite and coal, both
 previously exported in quantity, has been drastically
 reduced. One of the country's two textile plants
 has been heavily damaged, production in the small
 fertilizer and chemical industry has been curtailed,
 and the production of paper has been reduced by 80
 percent.
