Technical Writing for Defense & Government
Technical Writing for Defense & Government
Technical writing for complex platforms, systems, facilities, and regulated programs.
AEC supports defense OEMs, manufacturers, suppliers, integrators, military programs, and public agencies that need experienced technical documentation support.
We develop documentation used to manufacture, integrate, install, operate, maintain, inspect, troubleshoot, repair, and sustain complex products and systems. AEC works from engineering drawings, specifications, parts and logistics data, existing publications, contract requirements, and Subject Matter Expert input when needed.
Our quality management system is certified to AS9100D and ISO 9001:2015, supporting consistent planning, review, configuration control, and delivery.
AEC also supports aerospace technical writing, manufacturing technical writing, and transportation technical writing programs, and provides technical writing services, technical writing outsourcing and contract writers, and technical documentation services and solutions across industries.

This background helps our team:
- Interpret complex engineering and maintenance information
- Identify gaps, conflicts, and missing source data
- Provide practical feedback on procedures and content
- Work independently when adequate source information is available
- Collaborate effectively with engineers, maintainers, designers, and other Subject Matter Experts
When appropriate, AEC can also support onsite research, equipment observation, procedure validation and walkthroughs, and collaboration with production, test, maintenance, and field-support personnel.
Documentation We Produce
Technical, Operator, and Maintenance Manuals
Instructions for operating, inspecting, troubleshooting, repairing, and maintaining equipment and systems. Content may support operator, organizational, intermediate, field, or depot-level activities, depending on program requirements.
Manufacturing and Assembly Work Instructions
Step-by-step instructions for fabrication, assembly, installation, inspection, testing, rework, and other production activities. These documents help translate design requirements into controlled, repeatable work.
Illustrated Parts Information
Illustrated parts catalogs, illustrated parts breakdowns, repair parts information, exploded views, parts lists, quantities, and configuration or effectivity data used to identify and support equipment.
Installation, Test, and Field-Support Documentation
Instructions for installation, setup, integration, checkout, calibration, acceptance testing, removal, replacement, and field support.
Troubleshooting and Repair Procedures
Structured fault-isolation, diagnostic, corrective-action, repair, test, and return-to-operation information for technicians and maintainers.
Aviation and Airworthiness Publications
For defense aviation programs, AEC can also support maintenance manuals, component publications, illustrated parts information, Instructions for Continued Airworthiness, service information, and related aircraft documentation.

Platform Integration and Modification Support
Government and defense programs frequently adapt existing aircraft, vehicles, equipment, and systems by adding sensors, communications equipment, mission systems, defensive capabilities, and other specialized technology.
AEC helps document how these modifications are installed, integrated, operated, maintained, inspected, and supported.
We can also help coordinate information across the baseline platform and newly integrated equipment so that publications remain consistent as designs and configurations evolve.
Support at Any Scale
AEC supports emerging defense manufacturers establishing their first technical-publications baseline, established contractors that need additional program capacity, and larger primes or integrators seeking support for defined projects, supplier deliverables, backlogs, or specialized work packages.
We can serve as your technical publications team, supplement an existing team, or provide the writers and illustrators needed to manage a defined documentation effort.
Program Requirements, Military Standards, and Customer Systems
AEC can work from Statements of Work, contract requirements, applicable military and program standards, business rules, customer specifications, and established publishing requirements. These may include:
- S1000D
- MIL-STD-40051
- MIL-STD-38784
- MIL-STD-3048
- ATA iSpec 2200
- Program-specific and customer-defined requirements
During scoping, we confirm the applicable requirements, publication structure, format, review process, and required delivery files.
AEC can work within customer-selected authoring, publishing, product-lifecycle, and content-management systems.
The MIL-STD Documentation Landscape
Military standards (MIL-STDs) are the rulebooks that govern how defense documentation is written, formatted, and delivered. Buyers are often unsure which standard applies, partly because different standards control different things: some govern content and structure, others govern style and format, and others define the data architecture for electronic delivery. The standard that applies usually depends on the contracting service branch and the platform type. The plain-language explanations below describe these standards as general industry knowledge so you can map them to your program.
MIL-STD-40051 (Army Technical Manual Content and Structure)
MIL-STD-40051 is the U.S. Army standard for preparing technical manuals. It defines the work-package architecture (discrete, self-contained units of operating or maintenance information) and the content rules for those work packages. It is commonly seen in two variants: a page-based variant (often referenced as the -2 series) and an interactive variant (the -1 series) intended for electronic delivery. Army TMs authored to MIL-STD-40051 are typically tagged in XML against government DTDs and stylesheets.
MIL-STD-38784 (General Style and Format)
MIL-STD-38784 is the general style and format standard for technical manuals. Where MIL-STD-40051 governs what goes into a work package, MIL-STD-38784 establishes the house-style baseline: page layout, type conventions, warnings and cautions, change pages, and the requirements for electronic and PDF delivery. The two standards are complementary, and many programs cite 38784 alongside their content standard.
MIL-STD-3048C and S1000D (Air Force and Aerospace Data Modules)
MIL-STD-3048 (current revision C) implements S1000D business rules for U.S. Air Force technical content, and it references MIL-STD-38784 for style. S1000D itself is an international specification, maintained jointly by ASD (Europe), AIA (U.S.), and the ATA, that organizes content into reusable data modules stored in a Common Source Database (CSDB) and governed by a Business Rules Exchange (BREX). It originated for military aircraft and is now used across air, land, and sea domains, including via interactive electronic technical publications (IETPs). The exact revision a program cites (for example whether revision C applies) should always be verified against the ASSIST/quicksearch.dla.mil source for the contract in question.
ATA iSpec 2200 (Commercial and Military Aerospace)
ATA iSpec 2200 is the air-transport industry specification for aircraft maintenance and flight-operations content. It standardizes the chapter/section/subject (ATA chapter) numbering that organizes aircraft documentation and is widely used on both commercial and military aviation programs. AEC produces ATA iSpec 2200 data as part of its aerospace documentation work, and many programs blend ATA chapter structure with S1000D data modules.
Mapping Standards to the Service Branch
A useful first orientation is to map the governing standard to the contracting branch and platform. As a general guide:
- U.S. Army technical manuals are typically authored to MIL-STD-40051, with style per MIL-STD-38784.
- U.S. Navy technical manuals commonly cite Navy-specific standards (for example MIL-STD-3001 for NAVAIR aircraft technical manuals), with style per MIL-STD-38784.
- U.S. Air Force content is frequently authored to MIL-STD-3048C / S1000D business rules.
- Aerospace platforms across branches often use S1000D data modules and/or ATA iSpec 2200 structure.
Your CDRL and the cited DIDs are the authoritative source for which standard and revision apply. AEC reviews those requirements at the start of a program so the architecture is right before authoring begins.
How Defense Documentation Contracts Work (CDRL, DID, SOW)
Defense documentation is delivered against a defined contract mechanism, and understanding it helps a program plan realistically:
- SOW (Statement of Work) describes the work to be performed, including documentation.
- CDRL (Contract Data Requirements List), recorded on DD Form 1423, lists each data deliverable the contract requires.
- DID (Data Item Description) defines the content and format of each listed deliverable, often by pointing to the governing MIL-STD and allowing tailoring.
In practice, the CDRL and its DIDs determine which manuals and parts data you owe, in what standard, and at what milestones. AEC reviews these requirements at kickoff so the document architecture, illustration plan, and delivery format are correct from the first draft, avoiding rework later in the program.
Parts and Provisioning Technical Documentation
Provisioning data tells the government what spare parts, tools, and support items are needed to sustain a system, and in what quantities. It is closely tied to the parts data in the technical manuals but serves the supply and acquisition side of the program.
Provisioning Technical Documentation (PTD) is the family of provisioning lists (such as the provisioning parts list and related list types) that feed cataloging and spares buys. This data traditionally originates from Logistics Support Analysis (LSA) and the LSA Record (LSAR). The LSA/LSAR lineage has moved from the legacy MIL-STD-1388 series (now cancelled) to current guidance such as GEIA-STD-0007 and the international S3000L specification. AEC produces parts lists and the illustrated parts data that align with provisioning deliverables; the specific provisioning list types, data items, and source database are defined per contract.
Related Compliance Documentation
Two standards frequently appear in defense scopes of work but are often misunderstood as manual-writing standards. They are not. Both govern engineering activities, and the documentation around them is what a technical-writing team supports.
MIL-STD-130 (Item Marking and IUID)
MIL-STD-130 governs the physical identification marking of military property, including machine-readable Data Matrix marks used for Item Unique Identification (IUID). It specifies how items are marked with information such as the CAGE code, part number, and serial number. It is not a technical-manual authoring standard. Documentation that supports compliance with MIL-STD-130 includes marking plans and the IUID registration data that records how each item is identified.
MIL-STD-810 (Environmental Test Documentation)
MIL-STD-810 is an environmental engineering and laboratory test-methods standard covering conditions such as temperature, shock, vibration, and humidity. It defines how equipment is tested, not how manuals are written, and it does not involve performing the tests on the documentation side. The documentation that surrounds MIL-STD-810 testing is the test planning and test reporting that records the methods used and the results obtained, prepared by the program's test and engineering teams.
COTS and OEM Manual Conversion
Many programs start with commercial off-the-shelf (COTS) equipment or existing original-equipment-manufacturer (OEM) manuals that were never written to a military standard. Converting that legacy content is a recurring need, and document conversion is a core AEC capability. AEC restructures existing manuals into structured S1000D data modules or DITA/XML, reworks illustrations, and normalizes parts data so the content is ready to be tailored to your program's cited standard. Where the goal is a finished MIL-STD contract deliverable to a specific standard and revision, that adherence is confirmed during scoping. This is often the fastest path to compliance when usable source content already exists. See our technical documentation services for the full conversion workflow.
ISR and Platform Documentation
For intelligence, surveillance, and reconnaissance (ISR) programs, the documentation need is the same equipment-level material that any fielded system requires: operator and maintenance manuals, parts data, and sustainment documentation for sensors, ground stations, and host platforms. This documentation is written at the equipment level (how the hardware is operated and maintained), not at the level of classified intelligence doctrine. Specific program content, classification handling, and access requirements are defined during scoping.
What Our Customers Say
AEC has consistently demonstrated responsiveness, cooperation, expertise, affordability, and a high level of support.
Undisclosed Customer for Government and Defense Aerospace Programs
Controlled and Customer-Approved Environments
AEC maintains ITAR registration with the U.S. Department of State's Directorate of Defense Trade Controls (DDTC). Program-specific security, export-control, citizenship, U.S.-person, facility, and information-handling requirements are reviewed during scoping.
When regulated information must remain inside an approved environment, AEC may provide personnel who work through customer-furnished computers, systems, access controls, software, and required security training.
Some AEC employees have previously held security clearances. Any requirement for an active clearance or classified access must be confirmed for the individual and program.

Frequently asked questions
Mil-spec (military specification) technical writing is the production of operation, maintenance, parts, and provisioning documentation authored to military standards such as MIL-STD-40051, MIL-STD-38784, and MIL-STD-3048C / S1000D, and delivered against a contract’s CDRL and DIDs. It differs from commercial technical writing because the content, format, and data architecture are dictated by the standard and the contract rather than by house style.
It depends on the contracting service branch and the platform. As a general guide, U.S. Army technical manuals are typically authored to MIL-STD-40051 with style per MIL-STD-38784; U.S. Navy aircraft manuals commonly cite MIL-STD-3001; and U.S. Air Force content is frequently authored to MIL-STD-3048C / S1000D business rules. The authoritative answer is always your CDRL and the cited DIDs, which AEC reviews at the start of a program.
The Statement of Work (SOW) describes the work to be performed. The Contract Data Requirements List (CDRL), recorded on DD Form 1423, lists each data deliverable the contract requires. Each Data Item Description (DID) defines the content and format of a listed deliverable, often by pointing to the governing MIL-STD and allowing tailoring. Together they determine which documents you owe, in what standard, and at what milestones.
Yes. Document conversion is a core AEC capability. AEC restructures legacy COTS and OEM manuals into structured S1000D data modules or DITA/XML, reworks illustrations, and normalizes parts data so the content is ready to be tailored to your program’s cited standard. Where the goal is a finished MIL-STD contract deliverable to a specific standard and revision, that adherence is confirmed during scoping.
AEC has an office in San Jose, Costa Rica in addition to its Sandy, Oregon headquarters, so export-control posture (ITAR registration), security clearances, facility clearance, and US-persons-only staffing are confirmed during scoping rather than assumed. Bring these requirements to the kickoff conversation so the engagement is structured correctly from the start.
AEC works under either Time and Materials or Fixed Price engagements, and can provide in-house writers at its own facilities or embedded writers who work alongside your team. The right model depends on program size, security requirements, and how much of the work you want to keep on site.
