Groton — Forty-one Sailors of Class 15140 graduated from the Submarine Electronics Computer Field (SECF) Apprentice course on Nov. 19.

The SECF "A" school combines a core curriculum of electronics, fire control and sonar technician skills and abilities while emphasizing team training and cross-rating familiarization.

Seamen Jeffrey Lengermann, Joseph Menck and Jared Brimhall were class honormen.

Seamen Lukasz Osmanski, Daniel Delia and Shane Kern were recognized for personal excellence.

Seaman Apprentice Ryan Walker was meritoriously advanced.

The Submarine Electronics Computer Field Apprenticeship (SECF) training school is an eighteen-week course of instruction combining three ratings — sonar technician, fire control technician and electronic technician — in the same classroom, along with instructors from all three ratings.

SECF encompasses topics such as basic computer and electronic training and fire control systems, trigonometry and pre-calculus, AC/DC circuits, basic power supplies, digital systems, radar and microwave theory and operation, basic sound propagation, passive/active theory, gram analysis, oceanography, naval security, acoustic systems fundamentals, sonar underwater acoustics, acoustics analysis, submarine target motion analysis, computer technology and maintenance fundamentals, sonar watch standing and shipboard noise control.

Sailors learn theoretical and practical knowledge of their respective ratings in an interactive multimedia forum with emphasis on hands-on skills and team concepts.

Approximately fifty percent of the course is taught in the Combined Operational Acoustic Employment trainer (COAET).

The Sailors' learned and practiced skills are taught in four knowledge segments: basic maintenance, underway steaming, section tracking party and surface transit.

Graduating students are better prepared to meet the challenges of the fleet and have the knowledge and skills to be productive members as soon as they cross the bow of their submarine.
