Statement of Work (SOW) for Environmental Qualification Testing (EQT) of Combined All-domain Command and Control System (CAC2S) AFLOAT Data Processing Assembly and Workstation Mount

1.0 Scope

1.1 Purpose

This Statement of Work (SOW) defines the requirements for environmental and electromagnetic compatibility testing of the Combined All-Domain Command and Control System Afloat (CAC2S Afloat) Data Processing Assembly and Workstation Mount. The objective is to engage a qualified testing contractor to perform environmental qualification testing (EQT) to verify that this updated enclosure assembly and workstation mount meets all naval shipboard survival and operational requirements.

1.2 Background

The CAC2S Afloat system has undergone a hardware technology refresh, which changes multiple major pieces of equipment within the Data Processing Assembly and Workstation Mount. These changes alter the weight, center of gravity, power dissipation, thermal characteristics, and electromagnetic signature of this specific enclosure. Re-qualification is required to verify system integrity and compliance with shipboard environment standards.

The update is due by Close of Business (COB) each Friday.

7. Organize, host, and facilitate a monthly progress review meeting via Microsoft Teams to discuss overall project progress and milestones. Meetings shall occur once per calendar month at a date and time mutually agreed upon by the Contractor and the Government technical lead. The Contractor shall provide a meeting agenda at least two (2) business days prior to the review and distribute meeting minutes within three (3) business days following the session.

3.2 Government Furnished Equipment

The Government will provide the following test assets:

1. Data Processing Assembly (Approximate Dimensions: 60 inches height, 29 inches width, 41 inches depth; Approximate Weight: 800 lbs)

a. The enclosure requires two connections of electrical power (115 VAC, 60 Hz, single phase) and will be tested in an active/operational state during operational test phases.

2. Workstation Mount with Laptop (Approximate Dimensions: 17 inches height, 18 inches width, 16 inches depth; Approximate Weight: 50 lbs)

3.3 Detailed Test Requirements

The contractor shall conduct the following environmental and electromagnetic tests.

Data Processing Assembly and Workstation Mount:

Data Processing Assembly Only:

· Electromagnetic Interference (MIL-STD-461G): Conducted: CS101, CS114, CS115, CS116. Radiated: RS101, RS103.

· Operational Temperature & Humidity (MIL-STD-810H): High Temp (Method 501.7, Procedure II) at +33 deg C. Low Temp (Method 502.7, Procedure II) at 0 deg C. Humidity testing shall be tailored per Method 507.6, Procedure I (Induced), cycling relative humidity between a minimum of 20% RH and a maximum of 80% RH (non-condensing) over a 5-day (120-hour) test profile.

· Storage Temperature & Humidity (MIL-STD-810H, Method 501.7, Procedure I; Method 502.7, Procedure I; and Method 507.6, Procedure I - Induced): The Data Processing Enclosure shall be evaluated in an unpowered, non-operational state. High-temperature storage testing shall be conducted per Method 501.7, Procedure I at +70°C for a minimum of 48 hours (incorporating extreme low-humidity exposure down to 5% RH). Low-temperature storage testing shall be conducted per Method 502.7, Procedure I at -40°C for a minimum of 24 hours. Storage humidity testing shall be conducted per Method 507.6, Procedure I, Induced Cycle B1 (Hot-Humid Storage) to simulate high-humidity storage up to 95% RH.
