(6) Experience has shown that early engineering and design 
of naval vessels has significantly reduced the acquisition costs 
and life-cycle costs of those vessels. 
(b) SENSE OF CONGRESS.—It is the sense of Congress that— 
(1) the Department of Defense should carefully evaluate 
the maritime force structure necessary to execute demand for 
forces by the commanders of the combatant commands; 
(2) the Navy should carefully evaluate amphibious lift 
capabilities to meet current and projected requirements; 
(3) the Navy should consider prioritization of investment 
in and procurement of the next generation of amphibious 
assault ships as a component of the balanced battle force; 
(4) the next generation amphibious assault ships should 
maintain survivability protection; 
(5) operation and maintenance requirements analysis, as 
well as the potential to leverage a common hull form design, 
should be considered to reduce total ownership cost and acquisi-
tion cost; and 
(6) maintaining a robust amphibious ship building indus-
trial base is vital for the future of the national security of 
the United States. 
SEC. 132. SENSE OF THE SENATE ON DEPARTMENT OF THE NAVY 
FISCAL YEAR 2014 BUDGET REQUEST FOR TACTICAL AVIA-
TION AIRCRAFT. 
It is the sense of the Senate that, if the budget request of 
the Department of the Navy for fiscal year 2014 for F–18 aircraft 
includes a request for funds for more than 13 new F–18 aircraft, 
the budget request of the Department of the Navy for fiscal year 
2014 for F–35 aircraft should include a request for funds for not 
fewer than six F–35B aircraft and four F–35C aircraft, presuming 
that development, testing, and production of the F–35 aircraft are 
proceeding according to current plans.

(c) MOBILITY REQUIREMENTS AND CAPABILITIES STUDY 2018.— 
(1) IN
GENERAL.—The Director of Cost Assessment and 
Program Evaluation and the Chairman of the Joint Chiefs 
of Staff, in coordination with the Commander of the United
H. R. 4310—29 
States Transportation Command and the Secretaries of the 
military departments, shall jointly conduct a study that 
assesses the end-to-end, full-spectrum mobility requirements 
for all aspects of the National Military Strategy derived from 
the National Defense Strategy that is a result of the 2012 
Defense Strategic Guidance published by the President in Feb-
ruary 2012 and other planning documents of the Department 
of Defense. 
(2) MATTERS INCLUDED.—The study under paragraph (1) 
shall include the following: 
(A) A definition of what combinations of air mobility, 
sealift, surface movements, prepositioning, forward sta-
tioning, seabasing, engineering, and infrastructure require-
ments and capabilities provide low, moderate, significant 
and high levels of operational risk to meet the National 
Military Strategy. 
(B) A description and analysis of the assumptions made 
by the Commander of the United States Transportation 
Command with respect to aircraft usage rates, aircraft 
mission availability rates, aircraft mission capability rates, 
aircrew ratios, aircrew production, and aircrew readiness 
rates. 
(C) An analysis of different combinations of air 
mobility, sealift, surface movements, prepositioning, for-
ward stationing, seabasing, engineering, and infrastructure 
requirements and capabilities required to support theater 
and tactical deployment and distribution, including— 
(i) the identification, quantification, and descrip-
tion of the associated operational risk (as defined by 
the Military Risk Matrix in the Chairman of the Joint 
Chiefs of Staff Instruction 3401.01E) for each excursion 
as it relates to the combatant commander achieving 
strategic and operational objectives; and 
(ii) any assumptions made with respect to the 
availability of commercial airlift and sealift capabilities 
and resources when applicable. 
(D) A consideration of metrics developed during the 
most recent operational availability assessment and joint 
forcible entry operations assessment. 
(E) An assessment of requirements and capabilities 
for major combat operations, lesser contingency operations 
as specified in the Baseline Security Posture of the Depart-
ment of Defense, homeland defense, defense support to 
civilian authorities, other strategic missions related to 
national missions, global strike, the strategic nuclear mis-
sion, and direct support and time-sensitive airlift missions 
of the military departments. 
(F) An examination, including a discussion of the sensi-
tivity of any related conclusions and assumptions, of the 
variations regarding alternative modes (land, air, and sea) 
and sources (military, civilian, and foreign) of strategic 
and theater lift, and variations in forward basing, 
seabasing, prepositioning (afloat and ashore), air-refueling 
capability, advanced logistics concepts, and destination the-
ater austerity, based on the new global footprint and global 
presence initiatives.
H. R. 4310—30 
(G) An identification of mobility capability gaps, short-
falls, overlaps, or excesses, including— 
(i) an assessment of associated risks with respect 
to the ability to conduct operations; and 
(ii) recommended mitigation strategies where pos-
sible. 
(H) An identification of mobility capability alternatives 
that mitigate the potential impacts on the logistic system, 
including— 
(i) a consideration of traditional, non-traditional, 
irregular, catastrophic, and disruptive challenges; and 
(ii) a description of how derived mobility require-
ments and capabilities support the accepted balance 
of risk in addressing all five categories of such chal-
lenges. 
(I) The articulation of all key assumptions made in 
conducting the study with respect to— 
(i) risk; 
(ii) programmed forces and infrastructure; 
(iii) readiness, manning, and spares; 
(iv) scenario guidance from defense planning sce-
narios and multi-service force deployments; 
(v) concurrency of major operations; 
(vi) integrated global presence and basing strategy; 
(vii) host nation or third-country support; 
(viii) use of weapons of mass destruction by an 
enemy; and 
(ix) aircraft being used for training or undergoing 
depot maintenance or modernization. 
(J) A description of the logistics concept of operations 
and assumptions, including any support concepts, methods, 
combat support forces, and combat service support forces 
that are required to enable the projection and enduring 
support to forces both deployed and in combat for each 
analytic scenario. 
(K) An assessment, and incorporation as necessary, 
of the findings, conclusions, capability gaps, and shortfalls 
derived from the study under section 112(d) of the National 
Defense Authorization Act for Fiscal Year 2012 (Public 
Law 112–81; 125 Stat. 1318).
