Navy Knowledge Online (NKO) was a Navy learning and knowledge-sharing portal. The Navy announced its closure for April 14, 2017, with most training content moving to MyNavy Portal. If an old instruction points to NKO, start with the current official resource for the task you need.
What NKO was and when it closed
In 2003, NKO brought professional information, learning resources and collaboration tools into a portal intended to help Navy personnel find and share knowledge. Appian technology was part of the portal’s development at that time. That historical context explains why older course instructions and career references use the NKO name.
On April 6, 2017, the Navy published “NKO Content Shifts to My Navy Portal.” It announced NKO’s disestablishment on April 14 and said MyNavy Portal contained the majority of its training content. The announcement identified Navy eLearning, advancement information and personnel qualification standards among the resources available through the new portal.
The announcement describes the 2017 transition. It does not establish the current location or availability of every former NKO community, attachment or individual record. Use the subject and responsible organization to locate today’s guidance.

Choose an official starting point by task
| Your task | Official starting point | Access and next step |
|---|---|---|
| Find training or Navy eLearning | Naval Education and Training Command resource links | The public directory lists Navy eLearning, training catalogs and related resources. It labels Navy eLearning as requiring CAC login. Follow the current service instructions. |
| Find MyNavy Portal | NETC’s official MyNavy Portal link | NETC labels MyNavy Portal as requiring CAC login. The directory provides the official destination; this guide does not verify eligibility or account access. |
| Find personnel policies or career guidance | MyNavy HR | Public information is browsable. Specific transactions and linked personnel systems can have separate authentication and eligibility requirements. |
| Get personnel or pay help | MyNavy Career Center | The public page supplies current contact details and announcements. Use its current contact instructions for your inquiry. |
The NETC directory includes legacy browser wording for Navy eLearning. Obtain current device and browser guidance from the service’s official support route instead of treating every directory note as a current compatibility statement. Public link verification establishes the signpost; it cannot establish that a particular user can sign in or that a course is available.
The career-center page announces that the former AskMNCC@navy.mil customer-service inbox stopped being monitored on March 1, 2026 and points to its updated address. Check that page before copying contact details from an old document.
Resolve an old NKO reference
- Extract the task, course or document title, identifier, issuing organization and date from the reference. A title plus a course number is more useful than an expired portal path.
- Choose the official starting point above. Search for the subject or identifier and inspect its version and issuing authority.
- For assigned training, confirm the requirement with the responsible training office. A similarly named course may serve a different requirement.
- If the item is absent, give the responsible office the old reference and explain the task you need to complete. Ask for the current resource or disposition of the historical item.
- Update your local instructions with the verified official link, resource owner and check date. Keep the historical citation when it explains the origin of the requirement.
For example, a fictional 2014 checklist might say “complete the course on NKO.” Record the actual course title and identifier, then use NETC’s current training signposts and the assigning office to identify the appropriate route. The old portal name alone cannot determine the replacement course.
Use current access instructions
Some public Navy pages link to services intended for authenticated users. Follow the service’s stated CAC, account, device and network requirements. If access fails, record the service name, public starting URL, time and a non-sensitive description of the error for the official help route.
Do not bypass browser certificate warnings or enter credentials into unofficial NKO login pages. Avoid including personnel records, passwords or other sensitive details in an initial public inquiry. Let the responsible office direct you to its approved support process.
For historical research, distinguish evidence that a resource existed from evidence that it remains available. The Navy’s 2017 announcement provides a dated transition record; current public Navy pages provide the starting points for present-day tasks.
