  • Los Alamos was the site of the top-secret atomic weapons laboratory where the atomic bombs were designed and assembled.
  • Albuquerque provided essential support and resources to the Manhattan Project.
  • The legacy of this period can be explored through the historical sites and museums in both Los Alamos and Albuquerque.
  • The Manhattan Project brought together brilliant minds to create a weapon that changed the course of history.

Los Alamos Site Selection

During World War II, the selection of Los Alamos as the site for the top-secret weapons laboratory was a strategically important decision. The Manhattan District authorized the Albuquerque Engineer District to conduct a site investigation in the vicinity of the Los Alamos Ranch School in Otowi, New Mexico. The site was meticulously chosen based on several factors:


The location of Los Alamos allowed for easy transportation of personnel, equipment, and supplies. Its proximity to major transportation routes ensured efficient movement to and from the site.

Water Supply

Abundant water sources were essential for the laboratory’s operations. Los Alamos boasted reliable water supplies, which were crucial for various research and experimental processes.

Sparsely Populated Area

The remote location of Los Alamos, surrounded by sparsely populated areas, provided an ideal environment for secrecy and security. The low population density minimized the risk of accidental exposure and maintained strict control over the project.

Mesa Topography

The mesa topography of Los Alamos offered natural barriers that could be easily secured, thus ensuring controlled access to the site. The rugged terrain acted as a deterrent against unauthorized entry, enhancing the security of the laboratory.

Selection Criteria Description
Accessibility Proximity to major transportation routes
Water Supply Abundant water sources
Sparsely Populated Area Low population density
Mesa Topography Secure and controlled access

The careful consideration of these factors ultimately led to the selection of Los Alamos as the site for the top-secret laboratory. The location provided the necessary conditions for the Manhattan Project to thrive, resulting in groundbreaking advancements in atomic bomb development.

Design & Engineering

The design and engineering of the Los Alamos laboratory were supervised by the Albuquerque Engineer District of the Southwestern Engineer Division. To ensure the success of the Manhattan Project, the firm of W. C. Kruger was selected as the architect-engineer for the initial design and engineering.

The laboratory buildings and utilities were meticulously designed to meet the specific needs of the research and experimental processes necessary for the development of the atomic bombs. The engineers worked tirelessly to create a secure and controlled environment that would facilitate the groundbreaking work conducted at Los Alamos.

Design & Engineering Highlights
The design of the laboratory buildings incorporated advanced security measures to protect the highly sensitive research conducted within.
State-of-the-art utilities were developed to support the complex research processes, enabling the scientists and engineers to carry out their vital work effectively.
The design team collaborated closely with the researchers to ensure that all facilities met the specific requirements and scientific standards necessary for the successful development of the atomic bombs.

Thanks to their meticulous design and engineering efforts, the Los Alamos laboratory was able to accommodate the groundbreaking research conducted during World War II. The scientists and engineers at Los Alamos made significant progress toward the development of the atomic bombs, leading to the successful outcome of the Manhattan Project.

The Secret City

During World War II, Los Alamos became a tightly guarded secret city that played a significant role in the development of atomic bombs. To maintain the utmost secrecy, the town was not marked on any maps, and its location was known only to those involved in the project. Residents were strictly forbidden from disclosing their whereabouts to friends and family.

The secrecy extended to the town’s mailing address as well. Every resident, whether a scientist, engineer, or military personnel, used the same mailing address – P.O. Box 1663. This further ensured that the location of Los Alamos remained concealed from prying eyes.

Entry to the secret city was tightly controlled, with strict security measures implemented. Guards were stationed at multiple checkpoints to monitor and regulate access. Only authorized personnel were allowed in, and their activities within Los Alamos were known only to the select few involved in the project.

The Secret City: Key Features

Security Measures Secrecy Protocols Restricted Access
– Guards stationed at checkpoints – Location not marked on maps – Only authorized personnel allowed entry
– Tight control over information – Residents prohibited from disclosing location – Activities known only to those involved
– Classified research and experiments – Uniform mailing address for all residents – Strict security measures in place

V-Site and Gun Site

In the heart of Los Alamos, the V-Site stood as a historic landmark where the world’s first atomic device was assembled during World War II. This top-secret location played a crucial role in the development of the atomic bombs. The V-Site was characterized by its wooden and asbestos-shingled buildings, ingeniously fortified to minimize the risk of accidental explosions. Stored within these walls was the groundbreaking technology that would forever reshape the world.

Adjacent to the V-Site was the S-Site, where the lenses for the atomic bomb were meticulously produced. This site, although less known, was fundamental to the success of the project. Its contributions were vital in bringing together the key components needed to harness the immense destructive power of the atomic bomb.

Another significant location in Los Alamos was the Gun Site, where the gun-type weapon design was thoroughly developed and tested. This design would later be used in the creation of the Little Boy bomb that was dropped on Hiroshima. The expertise and innovation displayed at the Gun Site played a critical role in perfecting the design and ensuring the success of the atomic bomb.

These sites within Los Alamos are not only powerful symbols of the scientific and technological advancements made during World War II, but also serve as reminders of the immense responsibility that comes with harnessing such destructive power.

Notable Sites in Los Alamos

Site Significance
V-Site The assembly site of the world’s first atomic device
