PART I - STATEMENT OF WORK 

1.1. BACKGROUND 

The primary payload for the MOL System is a very high resolution 

photo-optical reconnaissance capable of operating in either a manual/ 

automatic mode in a manned system or a fully automatic-mode in an •unmanne 

system. 

To facilitate programming, budgeting, and advanced planning activities 

the MOL Program and Systems Offices have defined three "block" procurements 

of MOL systems as follows: 

a. _Block I: The present baseline seven-launch MOL Program which 

includes two unmanned sub-system qualification launches (no prime payload 

aboard), three all-up 30 day manned reconnaissance missions, and two all-up 

50-56 day unmanned reconnaissance missions. These vehicles are fully 

defined in appropriate MOL documentation and contracts. 

ID.. Block II: Procurement of 3-4 systems as an immediate follow-On 

to the Block I Program. The mix of manned and unmanned systems, has not. 

yet been determined. Consistent with-the payload capability of the Titan 

IIIM,.it is anticipated that the on-orbit duration of the manned system 

will be extended to approximately eorty days. A read-out system might 

also be added to the manned system to increase operational flexibility. 

Modest changes are anticipated in various subsystems to'eliminate.deficiencieS, 

increase flexibility, peak-out performance, and--in the case of the camera-,

c. Block III: Various concepts have been considered for Block III, 

ranging from increased booster performance for extended-duration integral 

launches, to space rendezvous/resupply operations for a continuous on-orbit 

DORIAN capability. For the purpose of this study, it should be assumed 

that the duration of the Block III manned system will be extended to 50-60 

days and the unmanned system to 70-90 days via integral launches. This 

also implies that the weight of the camera system could be increased by 

a few thousand pounds, if desirable, as long as the additions were consistent 

with the general present Laboratory and Mission Module configurations. 

Moderate to major internal Laboratory and Mission Module changes may be 

-Incorporated to accommodate a Mark II DORIAN camera system. 

This Work Specification describes Phase I of a two phase study to 

be performed by EKC to investigate improvements to the DORIAN baseline 

configuration which could be incorporated in the Block II or Block III 

MOL/DORIAN flights. The conceptual studies performed under Contract AF 

18(600)-2102, the contract definition work performed under Contract 

AF18(600)-2843, the transition work, long lead item procurement and Phase 

II effort performed under Ar18(600)-2864 form the basis of the program 

to be described in this work specification. 

1.2 Program Objectives 

The primary objective of this study is to identify, define and 

initially determine the effectiveness of modifications to the baseline 

DORIAN camera system considered most likely to provide measurable 

improvements in performance, quality, reliability, etc. In addition,

necessary future study efforts and/or technology projects are to be 

proposed which will more firmly establish the validity, definition and 

effectiveness and technical priorities of the selected modifications. 

The Phase I effort should be oriented to evaluation of technical. 

concepts affecting: 

a. Assurance and Improvement of Quality and Coverage 

b. Versatility 

c. Life and Reliability 

d. Areas Related to EK System Performance 

1.3 some 

The contractor will conduct.analytical studies, conceptual 

designs and limited experiments to identify, define and initially prove 

the feasibility of modifications of the baseline camera system (contract 

.AF 18(600)-2864) that can be logically incorporated into future phases 

of the MOL program. This effort may be considered as initial study toward 

the development of a MKII DORIAN camera system. 

Proposed changes may consider payload weight increases of not 

more than a few thousand pounds but should be compatible with the current 

orbiting vehicle external configuration. Moderate internal configuration: 

changes may be considered--for example, the internal laboratory changes 

necessary to accommodate a "relay lens and. sequence camera". 

The contractor will identify those areas requiring early study,: 

for possible inclusion into Block II orbiting vehicles to sequentially 

follow the baseline program and those areas where conceptual design

studies should be continued after the conclusion of this study as 

considerations for inclusion into Block III. 

In general the work will include the following: 

a. Studies to identify the most promising camera system 

modifications and establish a rational technical priority for each. 

b. Preliminary system: analyses of selected concepts to 

,the degree necessary to prove feasibility and to establish logical 

order of implementation. 

c. Modest laboratory experiments as required and feasible 

to support the system analysis. 

.d. Assessient of the recommended improvements in quantitative: 

and qualitative terms, both individually andAn conjunction with each other 

to derive a cumulative improvement in . resolution or general photographic 

quality. 

e. A proposal for a Phase II follow on study program to include 

identification or requirements for laboratory experiments, production of 

test breadboards as well as determination of new or modified test equipment 

and methods to demonstrate or evaluate the proposed concepts as defined in:. 

Phase I. The Phase II proposal should identify.appropriate interface 

exchanges and other requirements associated with the modifications proposed. 

The Phase I effort should give priority to those aspects which 

will materially improve resolution and general photographic quality. It 

should, however, also considr rather wide spectrum, evaluating technical 

areas affecting:
