C-5 System Description
(cid:132) Heavy-lift aircraft capable of carrying multiple tanks and
related equipment
(cid:132) Maximum take-off Gross Weight over 764,000 pounds!
(cid:132) Unique front and aft ramps facilitate easy drive-on, drive-off
loading of military vehicles and equipment
(cid:132) Accomplishes tasks that no other military aircraft can perform,
such as the new C-17, or any derivative of commercial aircraft
I n t e g r i t y - S e r v i c e - E x c e l l e n c e 11
C-5 Successful System
(cid:132) Over 34 years of successful operational performance in
support of the Nation’s cargo/transport needs
(cid:132) USAF inventory of 126 C-5 aircraft :74 C-5A, 50 C-5B, 2 C-5C
(cid:132) During Operation Desert Storm, C-5 fleet carried 46% of
the total inter-theater cargo, flying only 29% of the cargo
missions
(cid:132) In Operation Iraqi Freedom,
the C-5 fleet carried 48% of total
cargo flying only 23% of the cargo
missions

C-5 Synopsis
(cid:132) LP #1. Systems requirementsneed to integrate the User (warfighter),
planners, developers, and technologists into a well-balanced, well-
understood set of requirements
(cid:132) LP #2. Total Package Procurement Concept (TPPC)was a fixed-price,
incentive fee contract strategy for the design, development, and
production of 58 aircraft. Invented to control cost growth, it was the
underlying cause for the overrun
(cid:132) LP #3. A Weight Empty Guaranteewas included in the specification
and in the contract as a cost penalty for each delivered overweight
aircraft. This measure dominated the traditionally balanced
requirements resulting in a major shortfalls in wing and pylon fatigue
life
(cid:132) LP #4, Independent Review Teams (IRTs)were to assemble national
experts to examine the program and provide the best advice and
recommendations to the government in structures design, technology
and service life

C-5 Learning Principle
Highlight
(cid:132) Weight Empty Guarantee
(cid:132) Performance Specification limited Tradespace
(cid:132) Contract Penalty: $10,000 per pound per delivered aircraft
(cid:132) Goal: Manage cost growth as aircraft cost related to weight
(cid:132) Consequence
(cid:132) Negative effects of forcing
(out-of-balance) one aspect of
the system
(cid:132) Realize a trend in forcing
an aircraft from “nominal”weight

F-111 System Description
(cid:132) In 1950s, USAF needed a replacement for F-100, F-
101, and F-105 fighter-bombers
(cid:132) Mach 2+, 60,000 foot altitude
(cid:132) All-weather fighter, originally specified as capable of vertical and
short takeoff and landing (V/STOL)
(cid:132) Many firsts
(cid:132) 1st terrain-following radar, allowing it to fly at high speeds and
low altitudes
(cid:132) 1st production aircraft with variable
swing wings
(cid:132) 1st crew escape module
I n t e g r i t y - S e r v i c e - E x c e l l e n c e 17
F-111 Successful System
(cid:132) One of the most effective all-weather interdiction aircraft in the world
(cid:132) Established the best safety record of any aircraft in the Century Series
of fighters ---only 77 aircraft being lost in a million flying hours
(cid:132) First used in 1968 during Combat Lancer program, flying 55 night
missions against targets in North Vietnam
(cid:132) During Desert Storm in 1991, 67 F-111Fs operated from air bases in
Saudi Arabia.
(cid:132) Ability to deliver precision-guided ordinance in all-weather
conditions, they played a key role in the destruction of Iraqi key
targets in the Kuwait theatre of operations.
(cid:132) Flew 2500 sorties,
(cid:132) Destroyed 2203 targets
