The pace of de+elopment and technolo$ical obsolescence in the field of electronics necessitates a stron$ *esearch and (e+elopment base. This is all the more important in the area of (efense Electronics. BE, )ha?iabad has since its inception laid a hea+# emphasis on indi$enous *esearch and (e+elopment. About 5CE of its manufacture toda# relate to items de+eloped in1house.
