Course Overview:

Principles of Naval Weapons Training Course with Hands-on

This 4 day Principles of Naval Weapons Training course spans a wide variety of topics with the objective to provide the student the “big picture” as related to basic sensor and weapons theory. Material will cover general physical theory of various types of radar systems, electro-optical systems, sonar systems, guidance and tracking systems, command and control architectures, weapon propulsion, fusing and warheads. Mathematics expressions are kept simple such that a quick understanding of the relationships and trade-offs of different performance factors can be appreciated and determined. Considerations on how the differing elements of the Detect-to-Engage sequence could be analysed, judgments made and metrics used are also explored. All subjects will be treated in an unclassified nature.

Customize It:

• We can adapt this Principles of Naval Weapons Training course to your group’s background and work requirements at little to no added cost.
• If you are familiar with some aspects of this Principles of Naval Weapons Training course, we can omit or shorten their discussion.
• We can adjust the emphasis placed on the various topics or build the Principles of Naval Weapons Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).
• If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Principles of Naval Weapons Training course in manner understandable to lay audiences.

Audience:

This Principles of Naval Weapons Training course is designed for decision makers, analysts and engineers who want to broaden their understanding of individual elements of the detection to engagement kill-chain for Naval Weapons Systems.

Principles of Naval Weapons Training – Objectives:

Upon completing this Principles of Naval Weapons Training course, learners will be able to meet these objectives:

• Scientific and engineering principles behind systems such as radar, sonar, electro-optics, guidance systems, explosives and ballistics. Specifically:
• Analyze weapon systems in their environment, examining elements of the “detect to engage sequence” from sensing to target damage mechanisms.
• Apply the concept of energy propagation and interaction from source to distant objects via various media for detection or destruction.
• Evaluate the factors that affect a weapon system’s sensor resolution and signal-to-noise ratio. Including the characteristics of a multiple element system and/or array.
• Knowledge to make reasonable assumptions and formulate first-order approximations of weapons systems’ performance.
• Assess the design and operational tradeoffs on weapon systems’ performance from a high level.
• From this course you will obtain the knowledge and ability to perform basic sensor and weapon calculations, identify tradeoffs, interact meaningfully with colleagues, evaluate systems, and understand the literature.
