In recent years, the affordability of weapon systems has become increasingly important to policymakers in the Department of Defense and U.S. Congress. Aerospace industry analysts and some government officials have asserted that government cost estimates are based on outdated methods that do not account for the latest technological innovations. The authors of this report present the results of a RAND research study to update the methods for estimating military jet engine costs and development time.
Systems engineering and program management (SE/PM) constitute a large portion of the acquisition cost of military aircraft and guided weapons systems. The goal of this study was the development of a set of cost-estimating relationships that can be used to estimate the SE/PM cost element for development and
This report explores why, in recent decades, military fixed-wing aircraft costs have escalated beyond the rates of commonly used inflation indices, examining both economy-driven factors that the Services cannot control and customer-driven ones that they can. The authors found that this trend of cost increases is true for all types of aircraft
Legal mandates for airspace modernization, certification requirements, and minimum aircraft capability and equipment standards aim to improve the efficiency and safety of air traffic, particularly within the world's busiest airspace. Mandates drive changes in technical and operational standards, but they can also deny

The availability of efficient and cost-effective technologies to repair or extend the life of aging military airframes is becoming a critical requirement in most countries around the world, as new aircraft becoming prohibitively expensive and defence budgets shrink. To a lesser extent a similar situation is arising with civil aircraft, with falling revenues and the high cost of replacement aircraft.
Shocks in fluids result from fluid flow that is more rapid than the speed of
a compression wave. Thus there is no means for the flow to adjust gradually.
Pressure, velocity, and temperatures change abruptly, causing severe fatigue
and component destruction in military aircraft and engine turbines. This
problem is not limited to supersonic aircraft; many parts of subsonic craft are
The U.S. Department of Defense (DoD) faces a tightening budget in the coming years. Despite the lean budget years, unmanned aircraft systems (UAS) are expected to be a priority. Due to their usefulness for intelligence collection in irregular warfare (IW) and counterinsurgency (COIN), UAS were quickly fielded and sent to theater
The current strategic airlift fleet will be reaching the end of its service life in the next few decades, which has raised concerns about the cost and possible budget spike that would result from the need to recapitalize that fleet. This monograph presents the results of a cost-effectiveness analysis to determine
The classic supply-complement is beef and leather – an increase in the price of beef
increases the slaughter of cows, thereby increasing the supply of leather.
The opposite of a complement in supply is a substitute in supply. Military and civilian
aircraft are substitutes in supply – an increase in the price of military aircraft will tend
to divert resources used in the manufacture of aircraft toward military aircraft and away
from civilian aircraft, thus reducing the supply of civilian aircraft. Wheat and corn are
also substitutes in supply.
This report is one of a series from a RAND Project AIR FORCE project, “The Cost of Future Military Aircraft: Historical Cost Estimating Relationships and Cost Reduction Initiatives.” The purpose of the project is to improve the tools used to estimate the costs of future weapon systems. It focuses on how recent technical, management, and government policy changes affect cost. This report examines cost estimating risk analysis methods and recommends a policy prescription. The project was conducted within the RAND...

In recent years, most Cost Adjustment Sheets (CASs) have increased the Navy's Flying Hour Program (FHP) budget. They also have been far more utilized by the F/A-18 program than by program offices for most other types of naval aircraft. RAND assessed the contribution of CASs to the accuracy of FHP
