ASNE is the leading professional engineering society for engineers, scientists and allied professionals who conceive, design, develop, test, construct, outfit, operate and maintain complex naval and maritime ships, submarines and aircraft and their associated systems and subsystems.  ASNE also serves the educators who train the professionals, researchers who develop related technology, and students who are preparing for the profession.  Society activities provide support for the U.S. Navy; U.S. Coast Guard; U.S. Marine Corps; U.S. Merchant Marine and U.S. Army.

ASNE is the seventh oldest technical society in the United States.  It was founded in 1888 by a group of naval engineering pioneers, most of them officers of the U.S. Navy's Engineering Corps, who sought a unified approach to their profession in order to make the most of new advances in technology. The purposes of ASNE are:           

  • to advance the knowledge and practice of naval engineering in public and private applications and operations,
  • to enhance the professionalism and well-being of members, and
  • to promote naval engineering as a career field.

For 125 years, the Society’s objectives have been strengthened and preserved to meet the changing needs of a time-honored profession. Today ASNE conducts a variety of technical meetings and symposia, publishes the highly regarded Naval Engineers Journal and a number of other technical proceedings and publications, and fosters professional development and technical information exchange through technical committees, local section activities and cooperative efforts with government organizations and other professional societies.

The Society's annual meeting, ASNE Day, is typically held in February of each year in the Washington, DC, area. The meeting features major addresses by high level industry and government leaders and panel discussions by leading members of the profession.  It also includes presentation and discussion of technical papers on a variety of timely naval engineering topics, presentation of the Society's prestigious annual awards and a large exposition with government and industry exhibits covering the full spectrum of naval engineering technology. ASNE Day is highlighted by the Society’s annual Honors Gala, attended by hundreds of executives and senior managers from both government and industry.

Our website is designed to not only serve our members, but also to support scholars, students and others interested in the varied field of naval engineering.  We welcome your suggestions on ways we can improve your experience.

Welcome to FLEET

FLEET is an engaging engineering game that allows you to build, test, improve and compete in ship design. Be sure to use the engineering design process with (example handout) to organize how you design your ship and record your ships data. If you haven't played FLEET yet, click on the short video above to watch a 45-second overview. Schools taught physical science and the engineering design process with FLEET and now we hope to support your STEAM adventure at home. 











Quick Start advice

  1. Download FLEET:
  2. After you download the version, open it up and follow the prompts to install FLEET.
  3. Then, open up the game and let it update files until you get to the log-in screen.
  4. Creating your FLEET Account: Click "Don't have an account? Sign up now!"
    • To create an account, use the code: fleetrocks2018
  5. Please enter "Elementary Engineer", "Middle School Engineer", "High School Engineer" as your organization to compare your scores with your fellow engineering students. If you have any issues with this (or anything else), you can email us at fleet@navalengineers.org.
  6. QuickPlay! Budgets are terrible (but necessary); however, you can momentarily avoid them by choosing QuickPlay. Use the Mission Headquarters to complete the longer missions in the game.
  7. Drydock Interface: The + button in the upper left is for adding parts to your ship (creative design choice by us!). The ship button below that shows what is already on your ship. Hit the green play button to test out your ship.
    • If you want the User Guide, click here for all 44 pages of FLEET directions!
  8. Testing/Mission Interface: You can steer with the arrow keys, click on the rescue boat/helicopter to launch them, and get near or hover over seamen in need of rescue!


YOU can help FLEET this summer!

Our Discussion Page and home page, shows game-play and boat-building examples of our staff and our in-person events. If you have time, we would love to add a video, an engineering design process, or a picture of a boat you built. Students your aged and a little bit longer look up to you because you have taken the extra step of this internship. We would appreciate if you use your new found status to help us teach STEAM to communities across the country for free.

You may want to research an important engineer (like Grace Hopper featured to the right) or an important ship or an important naval yard.

You can talk with your internship, and you can email us (fleet@navalengineers.org) to jumpstart this process. Take a look at some naval engineering history and find ways to help us add more to this important narrative!

Common Engineering Problems:

            Problem: The boat is stuck in the drydock.

            Solution: Ensure the boat meets mission requirements, then click the green play button.

            Problem: The boat fails the Stability Test (weight is distributed incorrectly).

Solution: Usually the engine is not in the center of the boat. Also, look at the deck to see if objects are not symmetrically placed on the top of the boat.

            Problem: The boat is at sea and students don ’t know what to do.

            Solution: Hit “Esc” and “Restart Mission”. The directions will be in the upper left corner.

            Problem: Student’s helicopter can’t rescue people.

Solution: The helicopter needs to be directly over the people, keep moving forward and the button will appear to drop the rescue equipment.

            Problem: It's hard to resize the screen..

Solution: You could change this in Settings, but the easiest way is to hit CTRL+F for Windows (or Command F for Macs).

            Problem: The boat is stuck in the drydock.

            Solution: Ensure the boat meets mission requirements, then click the green play button.

FLEET in Elementary School Science

We work with upper elementary teachers to use FLEET as they introduce pushes and pulls (before we talk about forces!). These pushes can equal out as shown by FLEET looking vertically. The push from gravity and the push from the water balance out so the boat floats at the same level. We have classroom activities that support this understanding. FLEET also shows when forces are unbalanced. When the force of the engine exceeds the force from the water then the boat moves forward (or backwards!). Our materials have many hands-on activities that connect these forces in the virtual simulator with real-world experiences with these pushes and pulls. (Scroll down to see the list of activities.)

Check out an elementary activity today!

FLEET in Middle School Science

FLEET is perfect for showing the forces middle school curricula cover without emphasizing the numeric calculations used in high school. Students can study how gravity affects masses up to 2 million pounds. They can see gravity's effect on the object as a whole and on different sections of the ship. This force is balanced by the force of water, which is shown in each FLEET mission as well as in the simulator embedded into the curriculum. Students understand how mass is related to force and how these work together to make objects speed up (accelerate) and slow down (decelerate).

FLEET in High School Science

Most high school classrooms using FLEET employ it to demystify the physics equation, especially for students that do not have a strong math foundation. FLEET shows F = ma in stunning detail because these masses are not able to be replicated in classroom environments. Because FLEET is a video game, it can also re-engage students that are not engaged by traditional learning materials. The High School curriculum

Using Physics Simulators and the FLEET Video Game


We know kids are excited to "game" but using these virtual physics engines are more impactful than fun. Simulators give students the opportunity to control the physical environment and scientifically test for results with virtually no investment of time or money. Students can add or move weight, immediately see the effects as water lifts in the dry dock and then measure how it affects speed and turning ability. FLEET and the PhET simulators used in the curricula exemplify these materials.

For example, FLEET shows the relationship between force, mass and acceleration explicitly. Teachers know that force equals mass times acceleration. Students know that big characters move more slowly. FLEET lesson plans make the connection between force, mass and acceleration obvious while reinforcing the vocabulary that students need to use as scientists and engineers.
