The Applied Technologies Division was founded in 1975 as Jaycor, Inc., an employee-owned, advanced-technology company providing services to government and commercial clients. During the first 15 years, Jaycor focused on activities supporting the defense of the country against strategic nuclear attack. At the end of the cold war in 1990, the Company began to diversify, and at the same time implemented a strategy of building shareholder value by commercializing dual-use technologies originally developed under government funding.

The first product selected for commercialization was a line of high-speed host bus adapters used to connect workstations and large storage arrays in Storage Area Networks (SANs) using the Fibre Channel standard with speeds up to 2 gigabits per second. In early 1997 the Company reorganized, creating Jaymark as a holding company, JNI, as a separate subsidiary with the mission to become the leading provider of Fibre Channel hardware and software products, and Jaycor as a subsidiary to continue the government services business. Shortly thereafter, California Tube Laboratory, Inc. (CTL), a company that manufactures and rebuilds electron power tubes for both government and industrial clients, was acquired as a wholly owned subsidiary.

In October 1999, JNI was spun out as a public company in one of the most successful IPOs in San Diego history, with Jaymark retaining approximately 62% of the outstanding JNI stock. The Company was reorganized once again in July of 2000, whereby the JNI stock held by Jaymark was distributed to shareholders, Jaycor and CTL were purchased by the Company’s ESOP, and Jaymark was dissolved.

The second commercialization effort began as a division of Jaycor in 1999, and was spun out as a separate company, Jaycor Tactical Systems (JTS), in October 2000. JTS was created with the mission of developing, manufacturing, and marketing goods and services to assist law enforcement and corrections departments gain compliance with no lethal weapons, and to assist the general public with self defense. JTS’s first products were a line of Pepperball™ launchers and projectiles for use by law enforcement and corrections departments. JTS, now known as PepperBall Technologies, is planning to develop additional products for use by the public at large.

In January of 2002, Jaycor entered into a merger agreement with The Titan Corporation, a public company headquartered in San Diego. The merger was consummated on March 21, 2002, and effective that date Jaycor became a wholly owned subsidiary of Titan Corporation. The corporate cultures of both Titan and Jaycor focused on growing the core defense business, while at the same time commercializing selected defense technologies.

After the merger, Jaycor became known as The Advanced Technologies Group, headed by Mike Bell, under The Applied Technologies Sector, headed by Tony Frederickson. About a year later, L-3 Communications acquired The Titan Corporation. The collective defense and research technologies of Jaycor, combined with L-3's existing capabilities, results in a well-rounded and diversified defense and technology company, with unparalleled capabilities.
