------------------

FOR THE ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON OCTOBER 22, 1997

SOLICITATION

This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of SPARTON CORPORATION, an Ohio corporation (the

Company (the "Annual Meeting") to be held at the offices of the Company, 2400
East Ganson Street, Jackson, Michigan 49202, on October 22, 1997 at 9 a.m.,
local time, and at any and all adjournments thereof. The cost of solicitation

and its subsidiaries may solicit proxies personally, by telephone, facsimile or

At the meeting, the Company's shareholders will act upon the election of

As of September 1, 1997, the following table shows the shares of the
Company's Common Stock beneficially owned by the Named Executives identified in
the Compensation Table shown later in this Proxy Statement and all officers and
directors of the Company as a group (15 persons):

(3) Includes shares under options held by officers and directors exercisable

options exercisable within 60 days as described in this Proxy Statement.

Any Proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by (i) filing a
written notice of revocation with the Chairman or Secretary of the Company, at
or before the Annual Meeting, (ii) duly executing a subsequent proxy relating to
the same shares and delivering it to the Chairman or Secretary of the Company at
or before the Annual Meeting or (iii) attending the Annual Meeting and voting in
person (although attendance at the Annual Meeting will not in and of itself
constitute a revocation of a proxy). Unless revoked, the shares represented by
the enclosed Proxy will be voted at the meeting in accordance with any
specification made thereon, if the Proxy is returned properly executed and
delivered in time for voting. Unless otherwise specified, the Proxy will be
voted "FOR" the election of the four (4) director nominees.

Management does not intend to present, and does not know of anyone who
intends to present any matters at the meeting to be acted upon by the
shareholders not referred to in the Notice and this Proxy Statement. If any
other matters should properly come before the meeting, it is the intention of
the persons named in the Proxy to vote in accordance with their judgment on such
matters.

The shareholders of the Company have cumulative voting rights in the
election of directors at the Annual Meeting if notice in writing is given by any
shareholder to the Chairman, President, a Vice President or the Secretary of the
Company not less than 48 hours before the time fixed for holding the Annual
Meeting that the shareholder desires that the voting at such election shall be
cumulative. An announcement of the giving of such notice shall be made upon the
convening of the Annual Meeting by the Chairman or Secretary.

If voting at the Annual Meeting is cumulative, each shareholder will have
the right to cast that number of votes which equals the number of shares owned
by the shareholder multiplied by the number of directors to be elected, and the
shareholder may cast all such votes for one candidate or distribute such votes
among any number of candidates as the shareholder elects. The actual number of
shares required for election of a candidate will vary depending upon the total
number of shares voted. However, shareholders owning 1,565,619 shares, or
approximately 20% of the Company's outstanding shares, could elect at least one
director to the class of four directors to be elected at the 1997 annual meeting
for a term expiring in 2000 if there are five nominees.

ELECTION OF DIRECTORS

The following directors, previously elected by the Company's shareholders
and whose terms of office expire at the Annual Meeting, Messrs. James N. DeBoer,
David W. Hockenbrocht, Lawson K. Smith and Rory B. Riggs, are nominees each for
election to a three (3) year term expiring in 2000. The following portion of
this Proxy Statement contains additional information about these nominees.

A plurality of the votes cast at the meeting is required to elect the
nominees as directors of the Company. As such, the four (4) individuals who
receive the greatest number of votes cast by the holders of Common Stock will be
elected as directors. Shares not voted at the Annual Meeting, whether by
abstention, broker nonvote, or otherwise, will not be treated as votes cast at
the meeting.

It is believed that all four (4) nominees are, and will be at the time of
the Annual Meeting, available for election; and, if elected, will serve.
However, in the event one or more of them is or should become unavailable, or
should decline to serve, it is intended that the proxies will be voted for such
substitute nominee or nominees as the persons named in the proxy may in their
discretion select.

------------------------------------------------

COMPENSATION OF EXECUTIVE OFFICERS

The following tables provide certain data and information on the
compensation of the Company's Chief Executive Officer and its three most highly
compensated executive officers (other than the CEO) whose annual salary and
bonus exceeded $100,000 (collectively referred to as the "Named Executives").
This report addresses the Company's compensation policies and programs for the
year ended June 30, 1997, the details of which are reflected in the tables set
forth in the following pages of this Proxy Statement. The Company's and the
Board's policies and practices pertaining to the compensation of executive
officers and management have been in effect for a number of years.

EXECUTIVE COMPENSATION COMMITTEE REPORT

Decisions on the compensation of the Company's executive officers are made
by the Board's Compensation Committee. This Committee is composed of Mr. John J.
Smith, Chairman of the Board and Chief Executive Officer and four non-employee
directors; Messrs. Noecker, Kirk, DeBoer and Thompson.

The Company has long-established policies and practices intended to
compensate its salaried employees in a manner that will enable the Company to
attract, retain and motivate them to accomplish corporate goals and objectives.
These policies and practices encourage management to remain dedicated to the
maximization of shareholder value. The compensation of the Company's key
executives is based, in part, on the Compensation Committee's review of
executive compensation at other companies. The Committee's review entails a
comparison of executive' salaries at other companies for purposes of
ascertaining, in general, that the Company's salary structure is at or about
prevailing market rates. This review does not entail a quantative or qualitative
analysis of the components of the comparative executive compensation.

8

The Company's compensation program was comprised of several elements: cash
compensation (including salary and incentive bonus), incentive stock options and
defined benefit or defined contribution retirement plans. Reflective of the
Company's goal of relating compensation to corporate performance, the incentive
bonus compensation plan permits certain executive officers to earn additional
compensation if the pretax earnings of their operating unit is in excess of an
established goal. The performance goals for this plan are reviewed and approved
annually by the Compensation Committee. In addition, at the discretion of the
Committee, bonuses may be paid in addition to or in lieu of bonuses earned under
the incentive bonus plan based on the Committee's evaluation of the employee's
individual performance, level of responsibility and experience. During the past
fiscal year, both discretionary bonuses as well as bonuses under the incentive
bonus compensation plan were paid to the Named Executives.

The Company's Chief Executive Officer is compensated pursuant to employment
agreements that have been in existence since 1950. The employment agreement,
which expired on June 30, 1997, provided for a fixed base salary and an annual
cash bonus equal to 5 percent of the Company's pretax earnings in excess of $5
million, subject to an annual bonus limitation of $150,000. A further
description of the current employment agreement and related compensation of the
Company's Chief Executive Officer is set forth below under the caption
"Employment Agreement and Related Compensation."

Marshall V. Noecker Robert J. Kirk
James N. DeBoer John J. Smith
Blair H. Thompson

EMPLOYMENT AGREEMENT AND RELATED COMPENSATION

The employment contract with Mr. John J. Smith, the Company's CEO, expired
on June 30, 1997. Under the terms of that contract, Mr. Smith's annual salary
for fiscal 1997 was to be $302,969. The contract also provided for an annual
cash bonus equal to 5% of the Company's pretax earnings in excess of $5,000,000
with the bonus limited to $150,000 for the fiscal year ended June 30, 1997. For
the year ended June 30, 1997, Mr. Smith voluntarily reduced his compensation to
$261,716 and reduced the bonus payable to him to $25,000.

Pursuant to prior employment agreements with Mr. Smith, a deferred
compensation account had been established. Mr. Smith was entitled to receive
payments in monthly installments following termination of employment; or,
subject to prior approval of the Company's Board of Directors, from time to time
in lump sums upon Mr. Smith's request. In December 1996, Mr. Smith requested and
received the accumulated balance in his deferred compensation account
($2,288,518). In fiscal 1995, Mr. Smith requested and received $120,000 from the
deferred compensation account.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

- ---------------

(1) The options become exercisable cumulatively, beginning one year after the
date granted, in four equal annual installments. Optionees may surrender up
to one half of their unexer-

7
10

cised options in exchange for cash or Common Stock equal to the difference
between the current market value and the option price of shares issuable
upon surrender of such options.

(2) The exercise price equals the closing price of the Corporation's Common
Stock on the business day preceding the date of grant.

(3) The dollar amounts under these columns are the result of calculations at 0%,
5% and 10% rates compounded annually. They are not intended to forecast
possible future appreciation, if any, of the Company's stock price. An
alternative formula for a grant date valuation was not used, as the Company
is not aware of any formula that will determine with reasonable accuracy a
present value amount based on future or changeable factors. No gain to the
optionees is possible without an increase in stock price, which will benefit
all shareholders commensurately. A 0% increase in stock price will result in
zero dollars for the optionee.

OPTION/SAR EXERCISES AND HOLDINGS

The following table sets forth information, with respect to the Named
Executives, concerning the unexercised options and SARs held at June 30, 1997.
None of the Named Executives exercised any options for the purchase of Company
Common Stock during the past fiscal year.

(1) The value of unexercised options reflects the increase in market value of
the Company's common stock from the date of grant through June 30, 1997
(when the closing price of the Company's common stock was $11.875 per
share). The value actually realized upon exercise by the Named Executives
will depend on the value of the Company's common stock at the time of
exercise.

RETIREMENT PROGRAMS

The Company maintains a defined benefit retirement plan for employees of
the Company and one subsidiary which provide for monthly pensions following
retirement. During the past year, no cash contributions were made by the Company
to the plan as in the judgment of the Company's independent actuaries, the
pension plan was fully funded. The plan provides a basic benefit of $2.25 per
month for each year of credited service up to a maximum of $90 per month. In
addition, for those participants who contribute 5% of their monthly compensation
(excluding bonuses) per month, the plan provides for an additional monthly
pension amount equal to 1 1/2% of the participant's final 10-year average
monthly compensation (excluding bonuses) times the participant's years of
contributory and credited service to a maximum of 30 years. The following table
shows the estimated annual retirement benefits in specified remuneration and
service classifications upon normal retirement at age 65. The benefits shown are
not subject to any deduction for Social Security or other offset amounts. The
maximum amount of annual

compensation allowed to be included in determining final average compensation
has been limited by statute to $150,000 for 1997. This amount is subject to
future adjustment by the Internal Revenue Service.

Pursuant to Section 16 of the Securities Exchange Act of 1934, the
Company's directors and executive officers, as well as any person holding more
than ten percent of a registered class of the Company's equity securities, are
required to report any changes in their ownership of the Company's securities to
the Securities and Exchange Commission and the New York Stock Exchange. To the
Company's knowledge, all required reports were properly filed by such persons
during the fiscal year ended June 30, 1997.

PERFORMANCE GRAPH

The following is a line-graph presentation comparing cumulative, five-year
shareholder return, on an indexed basis, of the Company's Common Stock with that
of a broad market index (the S&P 500 Composite Index) and a weighted index made
up of selected S&P 500 indices including Electronics Defense (50%), Automobiles
(25%) and Industrials (25%). The Company selected this weighted index because
the companies included therein are engaged in operations similar to the
Company's historical operations, including the now discontinued automotive
operations. The comparison assumes a $100 investment on June 30, 1992, and the
reinvestment of dividends.
